I am trying to read a book that I've transferred from the public library to my Kobo ereader, and when I click on the book on my reader, I get the following message: Oops! This document couldn't be opened. This document is protected by Adobe Digital Rights Management (DRM) and is not currently authorized for use with your Adobe ID. Please sign-in with the authorized Adobe ID and try again. What do I need to do?
I am having the exact same issue and I am very unhappy with this. Adobe cannot help. Kobo cannot help. So, who can answer our question???
After numerous attempts at resetting the ereader, de-authorizing and re-authorizing, I also went through through the ereader in Explorer and removed what looked like 3 different adobe id authorizations. Seems they don't get refreshed. i decided to uninstall adobe digital editions. I installed version 3.0 for PC. I restarted my computer. When I added the library book to ereader from adobe digital editions, it asked to authorize the ereader, i did. Now i can read my library book on the Kobo Touch.
Hope this helps someone else as this has been a very time consuming and frustrating few days.
