I get books mainly from my local library. Frequently when I do so, after downloading and when trying to open the book, I get the following error message: Error dialog--Book has been returned, loan not on record." Local library can't explain it and I'm not sure if its a lending software problem or a Nook problem. Sometimes I can work around it by downloading a 2nd book. Then the 2nd book comes in fine and brings the 1st, failed one, with it. Sometimes that works but not always. Any ideas??
