      Previous discussions were for older versions of ADE.


      I am running ADE and Windows 10 (fully updated). I am on a relatively new computer and ADE worked the last time I used it on 22 July.


      Today when I download a book with ACSM I get the above message. Previous advice suggested de-authorising and re-authorising the computer. When I try this I get a message that effectively says I cannot do this and please try later.


      What can I do?

              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.
