When I download a library book, I get the error message "Error getting License. License Server Communication Problem: E_ACT_NOT_READY", as well as when I try to authorize my copy of digital editions to my account (in an attempt to deal with this.) I have used it to view ebooks from my college library successfully, though not recently.
I had the same problem, but there was no way I could erase the autorisation. The application refused to do it.

I tried the 6 steps you wrote above, with "desauthorize" for Macintosh. It didn't work. The desauthorize option could not be select, it was in gray.
I also tried another way that someone gave me here. Again, carefully, step by step. I would have to find it, I don't remember it by heart. Didn't work either.
Then I tried to download Adobe again. Was not successful.
After a full afternoon, I stopped. I was about to throw my mac by the window... 😕
Has you try the part with remove the activation.dat file?
Yes, thank you so much Nanaky!
I started the step 5: Navigate to /Users/Library/Application Support/Adobe/Digital Editions and drag the activation.dat file to the trash.
I found the library, using the Mac OS 10.7 steps, I found the Application Support file, then the Adobe file, but when arriving to /Digital Editions and drag the activation.dat file to the trash.
The Digital Editions file didn't exist. I looked again and again, I could find other Adobe files there, like Acrobat, but not The Digital Editions.
I made a search for the activation.dat file, and could not find it either.
I also tried this and was unable to Deauthorize, plus ADE didn't show in Library. Without deauthorizing, I downloaded ADE 2.0 for Mac and then restarted my computer. This WORKED! I can now open Epub files in ADE.
Here is a link for free ADE 2.0 for Mac and Windows: Adobe Digital Editions downloads
In the Finder, choose Go > Go to Folder.
In the Go To Folder dialog box, type ~/Library
Did not work. In Windows 7, I got to 6. Adept, but when I click on it, I don't see export, only Activation or Device.
I can get to Export by right clicking on Adept, but that only brings up my document window. No Export Range or opportunity to Select Range.
Very frustrating that every time I borrow a book, I run into a new problem with ADE.
Thank you! This is the correct fix. Works on my Windows 10 tablet.
Follow-up to above. I exported it to a file name and location, completed the other steps, re-authorized my ADE, and I still received the same "Error Getting license. License Server Communication Problem E_LIC_ALREADY_FULFILLED_BY_ANOTHER_USER" even though my account with the library where I borrowed the book has the same e-mail account as that on my ADE authorization account.
I have the same error. I completed the steps that lead to putting the activation.dat file into the trash, reinstalled and authorized and the same error, "Error Getting license. License Server Communication Problem E_LIC_ALREADY_FULFILLED_BY_ANOTHER_USER" keeps popping up. PLEASE HELP!!
& I have a MAC and the issue was not resolved.
Thank you thank you!!!!!!!!!!!!!!!!!!!
What about how to solve the same problem for the app on Android?
I just installed Adobe Digital Editions 4.5.1. For some reason, it automatically authorized itself using an email address that was my Adobe ID 15 years ago. When I try to de-authorize this long ao no longer working or relevant email, which is no longer my Adobe ID, it asks for a password. I do not have that password from 15 years ago (!) and I need urgently to get this Adobe Digital Editions authoroized with my CORRECT and CURRENT Adobe ID and password. I would have thought that this programe would have noted and used the CORRECT Adobe ID, given that my Adobe Creative Cloud was up and running tbhroughout this entire 'attempted installation' process. Any fast and efficient help will be hugely appreciated. Thank you.
Two more key bits: I am on a late 2019 Mac Powerbook running OS 10.15.7
Works on W10 HP Envy..Merci Beaucoup..
For Macintosh users, how exactly do you navigate to /users//library/application support/Adobe/Digital Editions?
