Every time I try to load a library book I get an error message that says: "Oops this document couldn't be opened. This document is protected by Adobe DigitalRights Management and is not currently authorized for use with my Adobe ID. I have tried de-activating my account and logging back as suggested on a chat with a customer rep, but that didn't work. The next person on chat told me to try this forum. I was always able to load library book before. This only started recently. Please help.
I am also having this issue. I have tried deleting the book from my computer and kobo touch, as well as de and re authorizing my computer and kobo. I have been able to use EPUB books before on my device. I am running Adobe Digital Editions 4.0.3 and Kobo Touch version 3.16.0.
