display problem?

i bought an arduino duemilanove and an lcd keypad module. im trying to upload mpguino and all i get is half the displaay lit up. not even letters or numbers just lit up. ive tried some of the examples for the arduino itself and it works. am i doing something wrong? the displaaaaay used to read "keypad test" until i tried uploading mpguino
