ADE 2.0 finally added support for the B&N DRM.
The unlock code are the credit card number and name of the default credit card of your B&N account.
And, no, it can't be bypassed.
Thanks so much for the information. However, I'm having a problem applying it. The full AMEx # and "American Express" are too big for the field provided. If I abbreviate to AMEX, it doesn't work. The number alone doesn't work. Any further suggestions would be greatly appreciated.
You need to ask B&N for exactly what they need.
I think the name part is your name as printed on the card, not the card issuer name.
