Having the same problem on both ADE 3.0 and 2.0. Able to open the downloaded library book into ADE and copy the book to the nook. However when I eject the nook the books do not show on the nook screen. I can reconnect the nook to the computer and ADE shows that they are there. Any ideas?
I have deauthorized the computer, reinstalled ADE, deleted the "digital editions" folder from the nook, reauthorized the computer, copied the books back to the nook. They show in ADE. But when I try to find them on the nook, they are not there.
