HELP PLEASE! before I throw this thing at the wall. After charging for about an hour, my reader popped up the page that says "opening book.." I cannot turn it off with the power switch at the top, can't change the page by pressing buttons, and have pressed the reset hole at the bottom numerous times with a pin to no result. reconnecting it to the power source does nothing either. does anyone have a solution to this or am I doomed to look at this page until the power runs out again? Thanks a lot.
