I used my Adobe Digital Editions really often and never had any problem.
Today, I tried downloading a book from the same site I always download it (public library) and it says: E_AUTH_BAD_DEVICE_KEY_OR_PKCS12
I've tried to unauthorized the mac, but ADE answer impossible to eliminate authorization.
I saw in in the forum the following instruction:
quit Adobe Digital Editions.
Navigate to /Users//Library/Application Support/Adobe/Digital Editions and drag the activation.dat file to the trash
But I don't have Digital Editon in the application Support:
Can you help me? Many thanks!
ADOBE is hopeless. I rather pay for this app to get some support!!!!
VERY BAD Adobe!!!
The same happens to me!
and i agree: very bad support from Adobe on this matter (only because it's a free application...)
