"Authorize Computer" not highlighted

[cheriew30569864]

I've just downloaded Digital Editions, when I go to "Help" to pair with a vendor, the option to "Authorize Computer" is greyed out. Help?

Try this:

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

    Remove the Adept Folder.

    In the Confirm Key Delete dialog, click OK.

    Close the Registry Editor.

    Open Adobe Digital Editions and reauthorize..
