Open Adobe Digital Editions and reauthorize.
I am having the same problem as many adobe digital users have had, with a new twist. I was unable to download materials from the public library, using cloud library. Using instructions from this forum, I deauthorized my computer. Now, when I try to reauthorize my computer, I receive the message
Activation Server error-code E_AUTH_BAD_DEVICE_KEY.
Digital Editions encounter an error on the activation server.
I'm sure I have the correct password because I changed it today when I began to have problems and needed it to log into this forum.
Could you help me with this?
Has you try the steps which i have write?
