I had a nook and was able to download library books on it to read. It messed up and the store ended up replacing it for me. I was able to read my library books on it for a few days and then all of the sudden the books I borrow won't even show up on ADE. I deauthorized and reauthorized my computer and nook and nothing happens. Why won't the books show up on ADE when I click for them to download? Thanks!
Possibly the books had an expiration date, just like other library books? Maybe if you re-download them, you can get them back. But your bookmarks will probably be gone. Good luck!
