If this doesnít work, perform a hard reset. This is done by finding the RESET button at the back of the handheld. Sometimes, this button might be near the bottom, under the battery cover. Press the RESET button using a pin or paper clip. With either method, you shouldnít lose any data.

Just in case you dont know, pulling the battery will do a reset. It's a common fix for a lot of things. Even old posts.
