I can not read my books in another device

[JakubStumper]

Hello ! I have iMac and have downloaded Adobe Digital Editions. I would like to authorize this system but it says me my Adobe ID was used in another mobile device. Is it not possible read my books in my iMac as well as in my iPhone ?? Thanks a lot for your help

Sometimes ADE gets its registration/activation confused and in a semi-authorized state.

Unfortunately, it often then gives misleading error messages about what is wrong.

Messages like those you are seeing seem quite a common form of wrone message.

Try completely removing any authorization using ctrl-shift-D to ADE (cmd-shift-D if on Mac).

Restart ADE, and then reauthorize with your Adobe ID.
