I am helping my grandma with a problem with her Aluratek Libre. Back in September I was able to put books on it using my ADE and hers with no problem. Now she is having problems getting books on it and when I brought it home to look at it I get these two messages alternating.

I'm not sure what to do to fix it.
I had this issue too. Go to the Adobe site and choose chat
Hopefully you will get Victor and he can reset your password to ADE and this will solve the problem. It fixed my issue. I kept getting this same error message when I tried to re-authorize my Sony e-reader. Good luck!
