Query: freezes!

The product worked great at first, but after awhile it started freezing on me. If I took out the battery and put it back in it would fix, but now it just freezes on the main screen, or it will get to the music and not play anything. I've done everything I can think of, and even tried looking at the manual, with no luck. Spend the extra money, it's worth it!
