For this problem, you need to deauthorize and authorize ADE again.

Launch ADE

Help -> Erase authorization.

ADE will be deauhorized.

Now again AUTHORIZE ADE

Help-> authorize computer.

Hi,

I am not sure if I had forgotten the password or it could not deauthorise as the message was unable to erase authorisation. Please try again later,

Thanks

To ensure that your password is correct, please try to login at "adobe.com". If your login is successful, that means your password is correct.

Also you can reset your password.

Coming to your second problem:

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

Mac: Navigate to /Users//Library/Application Support/Adobe/Digital Editions and drag the activation.dat file to the trash.

ADE will be deauthorized now.

Now Authorize ADE again.

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.
