Getting started with MPGuino. Need help with weird display.

Arduino uno, spark fun LCD, v0.86 (not sure what info you'll need to know).
Anyway I've been troubleshooting display issues and haven't gotten far. After power cycles, different editions of code, and double checking wiring, my display shows "Contrast, 000000000055 OK XX" and the LCD backlight and led from the transistor occasionally turn off and on. I can't make it change screens or anything with the buttons. What do I need to do? Thanks in advance!
