When a book expires and I borrow it again it downloads (and opens) fine to my computer, and appears to transfer to my nook simple touch, but when I go to open it on my nook it still says it's expired. I tried removing it from the nook library, and copying again, then it says it was returned. It seems like the record of the original borrow never gets replaced. I've tried both "replace" and "duplicate" with the same results. Anybody know how to completely erase the original borrow on the nook so it works like a new one ?
