I can't get it to work without logging into my B&N account. I don't see any way to bypass the sign in screen. If I disable WiFi, it still requires me to sign in & fails with no connection. Surely this app allows it's use without a WiFi connection once the books have been dnloaded. Thanks, kev Edit: This time after dnloading several books from my library the nook app doesn't ask to sign in. Now, if I select a book that was dnloaded, the Nook app tries to load it & then goes back to the library screen. I can only open one of the many that dnloaded. Maybe they are corrupted or maybe this app is crap!
