try this: when the player shows "updating library", perform a hard reset by pushing ">>|" and the play button until it turns off itself. if you push the play button now for a short time, you'll notice that the screen flashs for a second. wait about 10 minutes or longer until the screen no longer flashes by pushing play, then turn the player on again and it will format itself.

edit: or, if the message "updating library" appears, just wait up to ten minutes and it will update your music library!
