E_AUTH_BAD_DEVICE_KEY_OR_PKCS12 after Prior Success using Digital Editions. I've tried everything the forums recommend already.

I keep getting E_AUTH_BAD_DEVICE_KEY_OR_PKCS12 even though I've had success many many times on my mac. I've updated, uninstalled and reinstalled, unauthorized and reauthorized both the nook at the Digital Editions. What else can I do to read my library book? Through overdrive I can read the download on my phone, so there is no problem there. Why can't I read it on my computer???? I don't understand why this just started happening after many uses. I even tried clearing out Every single associated file... nothing...

I was able to figure it out using the help of another user who helped me REALLY deauthorize and then reauthorize my ADE. It worked, and my library books are back on ADE, AND I can reauthorize Nook properly (I was getting an error)!! The following is by a Staff Member Dominic Michael

"Please try the below steps (read the note section before clearing the registry):

Mac:

1. Deauthorize ADE. To do so, navigate to /Users//Library/Application Support/Adobe/Digital Editions and drag the activation.dat file to trash.
2. Authorize ADE again.

Windows:

1. Click Start > Run.
2. Type regedit and then press Enter. The Registry Editor opens.
3. In the left pane of the Registry Editor, locate the following registry key: HKEY_CURRENT_USER\Software\Adobe\Adept
4. Right-click the Adept key and click Delete.
5. In the Confirm Key Delete dialog box, click OK. ADE is deauthorized now.
6. Authorize ADE again.

Note:

Deleting the registry will deactivate all ADE authorization credentials on this computer. You will then be able to open eBooks on this computer only if you know your authorization credentials. Also you will not be able to open books that are fulfilled using anonymous accounts (authorized computers without an ID)."

THANK YOU Dominic Michael

Wenn ich ein Buch ins ADE 4.5. laden will kommt die Fehlermeldung: E_AUTH_BAD_DEVICE_KEY_OR_PKCS12

Aber leider kann ich meine Authorisierung nicht löschen. Seit einem Jahr steht immer wieder: versuchen sie es später!?? Was kann ich tun. (Mac user)

Thank you! Finally, this works. (De-authorising in Adobe Digital Editions itself did not work.) thanks 1 million!!!!!
