    Check Activation


      I have always been able to open downloaded E-Pub files in ADE version 3.

      Until now, that is.

      I now get the message "Error!  Check Activation" whenever I try to open a file in Version 3 or version 4.  I can't even get version 4.5 to work.

              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.
