I have a Kobo Aura dedicated e-reader which is authorised with Adobe digital edtions. Its been working fine for weeks with me downloading many library books until all off a sudden when I try and open a book it says "Oops! This document is protected by Adobe Digital Rights Management (DRM) and is not currently authorized for use with your Adobe ID [etc]..."
I have checked on my windown 7 laptop. The computer is authorised, the kobo device is authorised. I have tried removing the authorisation from the kobo and then authorising it again. Yet I still keep getting the same Oops error message.
I had made no changes to any settings on kobo or computer or adobe account prior to this error starting. One day it was working fine, the next day... Oops!
Has anyone got any ideas on how to rectify this? Any help would be greatly appreciated!!
