Hi, I think you might be making some progress as they have admitted there is a problem and they are trying to fix it, but might be barking up the wrong tree investigating the books, all the ones I tried about 10 did not open. I have asked customer care for the email address of Trevor Hunter CTO, not sure if they will supply it, as I want to escalate it to him. I live in the UK if anyone who lives in Canada could ring their office it might be an idea to get his email address or speak to him, their number in Toronto is +1 416-977-8737 If you want to go back to software from 2015, rather than factory reset, so you would have been running with this for most of 2016, this is how to do it: This is all from memory as I can't redo it on my Kobo. This procedure is written for people with reasonable PC skills but not an IT boffin. It means you will not be able to access any purchased books on your Kobo in future as with WIFI being turned off the books are not accessible but this fix works for the library books. Make sure that the Kobo Desktop is NOT running and you have WIFI disabled on your Kobo. Click or open this link, by right clicking and open in new tab or new window: Firmware 3.19.5761 - MobileRead Forums This page should appear: Under the first heading: Mark 3 Hardware: Original Touch(N905/N905B Model) select the link below it: http://download.kobobooks.com/firmwares/kobo3/january2016/kobo-update-3.19.5761.zip This will open a zip file, on my PC in the bottom left hand corner of the screen, click on this to unzip or open it. Connect your Kobo to the computer and select Connect on the device (if asked), making sure WIFI is still turned off to stop automatic updates. Open File Explorer. Locate where the zip file has been extracted to (kobo-update-3.19.5761). On my PC it was in "Downloads". Do not copy the original unopened zip file (kobo-update-3.19.5761) itself to the device, instead: Open the zip file. The zip file contains the following 3 items: Upgrade folder manifest.md5sum KoboRoot.tgz Select all 3 items together and copy the entire contents of the zip file to the .kobo directory on the Kobo. Safely remove the device from Windows (or your operating system of choice). Disconnect the device from your computer. The device will now install the new software on your Kobo. Do not switch WIFI back on as otherwise your Kobo will try to update its software back to the current version which we know does not work. This worked for me for library books using either version of Adobe 3.0 or Adobe 4.5 which makes me think it is a problem with the new Kobo software version and not Adobe. Let me know if it works for anyone. Hope this helps, if you need any more help or get stuck just ask.
