      I just upgraded to Adobe Digital Editions   on my Windows 8.1 machine. The hardware is ASUS and the antivirus is Kaspersky. McAffee was bundled with the machine, I don't use it, but I don't know if it is completely removed.


      I cannot add any new epub ebooks to my Adobe Digital Editions account, and so I can't access the ebooks from my local public library   eBook & Audiobook Collections - eBooks & Audiobooks - Subject Guides at Vancouver Public Library  after upgrading my Adobe Digital Editions as they suggested.


      Can I roll it back to 4.0?
