I have the Digital Editions 4.5 on my Windows 7. Downloading books on my Kobo reader has been a battle from day 1. I now am getting "error: check activation" . As suggested I am trying to de-authorize my reader in order to re-authorize it but ADE refuses my password. Any help would be appreciated.
Windows:
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.
Macintosh:
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.
