Using a Mac with OS X El Capitan 10.11.6 I got problems to authorise my computer. The error message is always "Activation server error - code E_AUTH_BAD_DEVICE_KEY"
The computer was authorised approx. 1 year ago.
What to do to overcome this problem ?

Open Adobe Digital Editions and reauthorize.

quit Adobe Digital Editions.
Navigate to /Users//Library/Application Support/Adobe/Digital Editions and drag the activation.dat file to the trash.
If you are using 10.7, see https://helpx.adobe.com/x-productkb/global/access-hidden-user-library-files.html
Open Adobe Digital Editions and reauthorize.

Thank you for the advise. However, it did not solve the problem, the message is the same.
The credentials are correct because I could authorise other devices e.g. Tolino e-book reader.

You get the same error message after the remove and authoirze again?
Only by one eBook or when open Digital Edition?

Correct, I get the same error message after removing and trying to authorise again.
This happens when opening Digital Edition and authorising under Help menu as well as authorising trying to open an eBook
