I can't load ebooks from ADE to my Nook. I have tried a bunch of different things. I am now trying to deauthorize my account to see if that allows me to remove the library card that somehow is attached to the account. However, when I try to deathorize i get a message asking for a vendor id and password. I do not know what to put in there. My library has told me that they don't have a vendor log in and I have tried my own and it won't take it. I am beyond frustrated. I have been trying to fix this issue for months, and no one can help me!!
