I just downloaded ADE to be able to sideload non-Barnes & Noble books to my Nook. The process went smoothly. I was directed to a library of free e-books carried by ADE. I downloaded two of them successfully. When I went back to my account to drag and drop the books to the Nook icon, an excerpt of the second of the two books I had downloaded was on the screen; I am unable to close the screen in order to access my account into. There are no options on the screen except for those that pertain to that book.
Just for clarification, the screen I keep referring to is the ADE one that displays all the books that have been downloaded to/by ADE--not a Nook screen.
I just restarted my computer and was able to access my account page. I have another problem now, though, which I'll address in a new topic if I can't figure out how to fix it by tomorrow...
