Kobo won't open library book because eReader was previously deauthorized [2018]

I have a Kobo Glo and I am now getting the following error message "Your eReader is not authorized to open this book. Because you previously deauthorized your eReader, you need to reimport the book using ADE". I have tried reimporting the book, and even returning the book and then reborrowing it before reimporting it to my Kobo. I have tried deauthorizing the reader and then reauthorizing it before reimporting it to my Kobo. Deauthorizing and reauthorizing my Kobo worked a couple of times, but not any longer. I have uninstalled my version of ADE and downloaded and installed the latest version. I have contacted Adobe and they checked my Adobe account and authorizations and was told that I still have unused activations and my authorizations appear to be in order. I can read my books on my MacBook using ADE, and I can even read them using ADE when I click on my Kobo icon in ADE sidebar and open the book. ADE seems to be working as advertised, but my Kobo is not cooperating. I have contacted Kobo as well and they say it's an ADE issue and will not discuss it further. I have not done a factory reset on my Kobo as I don't want to lose all my purchased eBooks. I have checked out a few threads regarding similar issues, but none with my particular error message. Any suggestions are appreciated as I feel I have tried everything, save a Kobo reset, or trashing the Kobo altogether. Thanks

    Adobe only has ADE 4.511 and 3.0 on this page. I was using 3.0 then had problems with ADE opening/getting  the library ebook I borrowed from Overdrive. Then I used 4.511 with some success but the authorization problem started. Being able to open the borrowed ebook via ADE on the computer and kobo (via ADE) doesn't necessarily mean that when kobo is unplugged from the computer, kobo will be able to open said ebook. That's what has been happening to me before I found this forum. I tried to go back to ADE 3.0 but it won't worked on my Windows 7 anymore. It keeps crashing.

    This is where I found 2.0. I de-authorized both computer and kobo. Downloaded again from the library the problem ebook. Before download started, I was prompted to authorize my computer. Re-authorized kobo. It worked! Kobo can open a borrowed library ebook without being plugged in to the computer.

     

    Good luck!


    Hi,

    I spent hours trying to get my Kobo Aura HD to open a library book I borrowed through Overdrive and I can confirm that the issue is with Adobe Digital Editions (in particular v. 4.5) and indirectly with Kobo and Overdrive because none of them care enough to create a long-term solution. I'm running Windows 10. After trying and failing to get a number of the posted solutions to work I stumbled across something that worked for me and my ancient Kobo. I hope these steps will work for others, and will assume anyone trying them has a basic understanding of how to authorize/deauthorize and install/uninstall on both Windows OS and the Kobo.

     

    To start, the Kobo should not be connected to your computer.

    1) Delete the books that you can't open off your Kobo.

    2) Via Settings on Kobo:

      2a) Ensure your date and time are correct on your Kobo and you have wifi turned on.

      2b) Open Accounts and deauthorize your Kobo from the Adobe account.

    3) Delete the books you downloaded from your computer. You can do this within the Adobe Digital Editions app on your computer by hovering over the book with your cursor and right clicking then selecting "Remove from Library". Also delete the .acsm file from the Downloads folder.

    4) This step probably doesn't matter, but it doesn't hurt either. With the ADE app open, press Ctrl + Shift + D. A window pops up with Erase Computer Authorization. Go ahead and Erase Authorization.

    5) Uninstall ADE version 4.5 from your computer.

    6) Go to this third-party website and download version 3.0 of ADE. https://adobe-digital-editions.software.informer.com/3.0/

    7) Install ADE version 3.0 on your computer and login using your Adobe account and password.

    😎 Within the ADE app, authorize your computer under the Help menu or by pressing Ctrl + Shift + U.

    9) Open a web browser, go to your Overdrive library page, go to Loans, redownload the book you originally had trouble with.

    10) Once downloaded, double click on the .acsm file and it will open in ADE version 3.0. Close the book by returning to ADE's main Library page.

    11) Connect your Kobo to your computer. It will appear on the left panel of ADE.

    12) Drag and drop the book from your open Bookshelves folder onto the Kobo.

    13) Eject your Kobo from your computer and wait until Kobo updates content before unplugging the USB cable.

    14) Open the book on your Kobo and enjoy.

     

    As I said, this solution may not work for everyone but it did work for me on my old school Kobo Aura HD. I really hope it helps and prevents someone from using their Kobo as a Frisbee.

    I had the same issue and this is how I fixed it (after trying tons of other stuff).  I went into the settings on my kobo (not when connected to laptop) and under "Accounts" I deauthorised my adobe account.  On my laptop, I uninstalled ADE 4.5 then reinstalled the same version.  I then connected my kobo to laptop and downloaded my books again (I did try to reauthorise my kobo on ADE but couldnt as the option was greyed out).  Then when I tried to open the books on my Kobo, it actually worked.  Not sure which of these steps actually fixed the issue, but I can now read library books again, yay!

    After months of trying to download and read books fom my library to be faced with the 'you are not authorised to read this book' - unauthourisinbg and reauthourising the reader and computer, my loccal library came up with the definintive answer!! It's not Adobe  or the library , It's Windows 11... at their suggestion I tried to download my library books as I used to on my old windows 10 laptop ... no problem whatsoever!! I've tried this several times and again no problem - it's Windows 11 that's the problem , it's  not compatable with Adobe , no one wants to high light this , but the proof is in the useage. Just try it!

    Honestly, nothing I try anymore seems to work. I fault both Adobe and Kobo for making products that don't work properly, and then completely washing their hands of any responsibility when their customers have problems. Because of this unrelenting problem between Kobo and Adobe, I have been forced to start reading my library books on my apple mini ipad with the Libby app, where everything from the library downloads hassle-free. I preferred reading books on the smaller-format Kobo, but what's the point, if I can't read any library books? I will never buy Kobo again and if I never have to deal with the Adobe Digital Editions program again, I will be a very happy person. Shame on these two companies for not stepping up and solving their compatibility problems for their customers!!!

    Well said indeed. Why make stuff that doesn't work properly? Have you tried my suggestions in this loooooong trail? I also think leaving an expired book or two on your Kobo and ADE helps.  This is pure superstition but the last time I cleared all the expired books I got the error again. Good luck!

    Hello again, I just thought I'd post again to keep the chain going. I forgot my own advice and had to re-read these posts. So, this time:

    1. Right click on books and 'Remove from library' for both ADE and Kobo EXCEPT one expired book (I'm not sure about this but I'm going to try it).

    2. Download the books I wanted to borrow + 1 fresh book.

    3. Drag ALL books from ADE to Kobo in ONE go.

    Worked!

    Cheers!

    Hi,

    I keep at least one expired book on my Kobo. I always click and drag more than one book from ADE to Kobo. Haven't had the problem since. Fingers crossed.

    I eventually got it fixed.

    1.  Got a new ID by getting an Overdrive account, and authorising ADE 4.5 with that.
    2. Logged into my library and downloaded my borrowed books
    3. After copying them to my device I opened them in ADE from the Device (the copy of the file on the device)
    4. Disconnected my Kobo Glo and read the books on there.

    I'm not sure which step solved it. I think the most important thing is to open it in ADE from the device. Doing that I was able to open books that were previously closed to me. Sometimes the covers still don't show, but at least you can read the books.

     

    You'll need to re-download any books you had tried to copy to the device before. If you have changed your authorisation you will need to return and re-loan the book.

    I have been going through this issue and nothing worked. The only solution that ended up working was deauthorizing my computer, deleting all books from ADE, uninstalling ADE 4.5 and installing version 3.0 instead, then going through the normal steps of authorization and adding books. The installer for ADE 3.0 can be downloaded here:https://download.adobe.com/pub/adobe/digitaleditions/ADE_3.0_Installer.exe

    I work in IT and it took me a while to resolve this issue. I have tried de-authorizing/re-authorizing both desktop and Kobo eReader, factory reset the eReader (with limited success), uninstall and re-install ADE (same version 4.5.11), return my library ebook and borrowing again and download epub but nothing seemed to help.

    Issue started after I reset my desktop so I concluded it must be the ADE version because I never had this issue in the past. Fortunately I was able to find ADE 2.01 from my backup, installed it and de-authorized/re-authorized both desktop and Kobo, borrowed the same book that had the issue opening on eReader, downloaded epub and copied to eReader and voila, issue resolved.

    Moral of the story: there seems to be something in ADE 4.5.11 that is causing the issue.

    THANK YOU!!! This totally worked! Omg, like the others who posted replies in this thread, I wasted hours trying to unauthorize and reauthorize my computer, Kobo, deleting and re-downloading the library ebook in question. It really seems like the solution is to add a non-DRM book in between! Too bad the official Kobo and ADE "help" pages don't tell you this. (Also, it's been four years since your solution post and this is still a problem.) Thanks again!
