Why ADE doesn't specify the information it requires to unlock a book is beyond me. But yes, my name and credit card on file with B&N did the trick for me, too. Thank you.
I'm having a very similar problem. I downloaded a play script from the publisher and I think I blew past the Adobe ID part (I already had an ID). I initially could open it (vendor ID) on laptop but not on android device. When I tried the CTRL+Shift+D to reauthorize, I have now lost it on every device! Any suggestions? (Short of buying it again)

Okay, I think I have figured it out. I purchased a book from Barnes and Noble, and when I downloaded it I recieved the message for a username and unlock code. The username is the name on which ever card (visa, mastercard, amx, ect.) you used to purchase an ebook and the unlock code is the card number. If you borrow an ebook from the library you would use your library card number and password. I hope that helped to answer your question.
It may vary from library to library, but when I borrow a library book (Hampshire, UK) I need my card number to check out and download the .acsm file from the library Overdrive website, but then the authorization to ADE is my Adobe ID.
I was just given a Nook book as an e-gift from Barnes & Noble. I got the same message in my Adobe Digital Editions about the username and unlock code when trying to open it with ADE and initially couldn't find anything to make it work. However, when I turned on my Nook wi-fi and reloaded its library, it downloaded right away to the Nook. It only appeared in ADE when I had the Nook connected to ADE, but still couldn't open it without the username and unlock code. The gift giver's name and credit card number also didn't work. Then I found the answer in B&N's community forum... What worked was my name and credit card number on file in my B&N account.
