You can only authorize your computer with an Adobe ID that has not been used for authorisate a computer or mobile

Hello,

I bought a new E-book and tried to copy it to the ereader (bebook). Then the error came along.

On another site i was suggested to unautherise  the bebook and re-autherise it.

OverDrive | What to do if you get a "CE_COPY_NO...

Now i am unable to autherise the computer and the bebook.

Wat is going wrong ? Is is possible to fix this problem?
