    Error Message


      I get the following error message (

      Error getting License. License Server Communication Problem:


      )when I try to open a downloaded book from my public library in Digital Editions. I am using a macbook pro 10.8.5. This is a new computer that I just migrated the files to from my old macbook where this all worked.

          You probably need to deregister and reregister ADE on the new computer.

          Migrating the files will have left ADE authorization in a funny state.


          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.
