All of a sudden I'm getting these "Sorry! messages that trad "This application Books (process com.google.android.apps.books) has stopped unexpectedly. Please try again." and there is a button at bottom to Force Close? It's not only "Books" it's "Music" and "Games" that give the same message? Anybody got ideals on how to correct this, I've had the Le Pan lock up a couple times and had to push the little reset on the back but that doesn't help either?
