I have the 7" White PD Novel. When I go into the Barnes and Noble app I can see everything in the My Novel tab, but when I click on B&N Bookstore or B&N Library it pops up with "Sorry! The application B&N (process net.pandigital.reader) has stopped unexpectedly. Please try again." The button below this says Force Close. It was working fine until I took out the old internal memory card and copied everything over to a new one. Did I not copy things over correctly? How do I fix this?
