Which error message you get exactly?

[johnt2071451]

Thank you for responding.

The verbatim message. The message box is from Digital Editions.

Unable to Download.

Error getting license. License Server Communication Problem:

E_AUTH_BAD_DEVICE_KEY_OR_PKCS12

I hope this info points toward a solution. Thanks again.

This looks promising but in my Registry Editor I couldn't find Software/Adobe.

HKEY_CURRENT_USER has hundreds of subfolders, but no “Software”.

My Registry Editor has four other folders. When I searched for Adobe, it only appears in the following location:

Folder: HKEY_CLASSES_ROOT

subfolder "acrobatsecuritysettings"

item Content Type RG_SZ. Data "application/vnd.adobe.acrobat-security-settings"

When I searched for adept, it appeared in the same folder, then subfolder "acsm"

Content Type RG_SZ, item "application/vnd.adobe.adept+xml"

Do you think these files can be used to proceed with your instructions 6 through 11?

Thank you again.

Do used a normal user or a network user?

[johnt2071451]

I'm a normal user.

[Nanaky]

Then you should have the registry. But you has install the software as admin?

[johnt2071451]

Nanaky,

This is just to thank you for your efforts to help a stranger.

I'm giving up. I tried uninstalling ADE and installing it anew but that didn't help. I can still use my Nook for everything except borrowing library books.

Digital Edition are by uninstall not remove the registry for the authorize. This can do only over the registry or the menue point.
