I'v tried uninstalling and then reinstalling Digital Editions (both v2.0 and v3.0) with same result. I have receintly had a hard disk crash and this is the first time I've used Digital Editions since I've restored from backup onto a new hard dirve. Any ideas?
Sometimes ADE gets its registration/activation confused and in a semi-authorized state.
Uninstalling and reinstalling does not help.
Unfortunately, it often then gives misleading error messages about what is wrong.
A common incorrect message informs you that the ID is already in use on another computer and cannot be reused.
This can often be resolved by completely removing any authorization using ctrl-shift-D to the Library screen on ADE (cmd-shift-D if on Mac).
Restart ADE, and then reauthorize with your (old) Adobe ID.
In extreme cases on the mac, the following extra step has helped. 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 Access hidden user library files | Mac OS 10.7 Lion. (http://helpx.adobe.com/x-productkb/global/access-hidden-user-library-files.html)

Thanks, this worked.
