    ADE 2.0 computer authorization


      ADE 2.0 will not let me authorise my computer.  When I try to do so, I get the message, "You can only authorize this computer with an Adobe ID that hasn't been previously used to authorize any other computer or mobile devices."  Is that really true?  I need to get a new Adobe ID every time I want to authorize a new computer?

          Whatever you do don't get a new Adobe ID if you still want to read your old books.


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

          Uninstalling and reinstalling does not help.

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

          A common incorrect message informs you that the ID is already in use on another computer and cannot be reused.

          This can often be resolved by completely removing any authorization using ctrl-shift-D to the Library screen on ADE (cmd-shift-D if on Mac).

          Restart ADE, and then reauthorize with your (old) Adobe ID.

          In extreme cases on the mac, the following extra step has helped some people.  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 Access hidden user library files | Mac OS 10.7 Lion. http://forums.adobe.com/thread/1265248?tstart=0

            Thank you.  Deauthorizing and then reauthorizing worked.  I don't understand why that made a difference, but it's working now, so I guess not too important.
