    My license key is damaged


      I cannot open my purchased documents, getting an error message that my license key is damaged.


      I tried to erase my authorizations, but keep getting the message "Unable to Erase Authorization. Please try after som time".


      Can you please help?

          If you get a error that license key damage it is a problem with the eBook itself. Try to download with a other internet browser. If not help you should contact the reseller of the eBook to check the file itself.


          To remove the authoirze used this:



              Close all applications.

              Choose Start > Run.

              In the Open text box, type regedit and then press Enter. The Registry Editor opens.

              In the left pane of the Registry Editor, locate the following registry key: HKEY_CURRENT_USER\Software\Adobe\Adept

              Select the Adept key.

              Choose File > Export.

              In the Export Registry File dialog box, select Selected Branch under Export Range. Enter a name and location for the backup registry key, and then click Save.

              Right-click the Adept key and choose Delete.

              In the Confirm Key Delete dialog, click OK.

              Close the Registry Editor.

              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.
