Error! Check Activation.

Question

I loaded Adobe Digital Editions version 4.0.3 and authorized my computer. When I try to drag a file (e-book checked out from libary) to adobe digital editions I get the following error:

Authorization information shows the computer is already authorized. When I try to erase authorization I get the following message:

Unable to erase authorization. Please try after some time.

Authorization remains even when software is uninstalled and re-installed.

I am running the following:

OS Windows 7

Kaspersky PURE 3.0 for security

If due to some reason, you are unable to deauthorize ADE, follow the below steps:

Windows:

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

Right-click the Adept key and choose Delete.

In the Confirm Key Delete dialog, click OK.

Your authorization will be deleted.

ADE will be deauthorized now.

Now Authorize ADE again.
