I had my tuner lock up on me when i first got it. the screen kinda froze up at certain point in the process. it was just a bad one. called hte guys at H&R adn they got me a new one in like 2 days. I'd call them ASAP and see if it's something you're doing or it's jsut locked up. they are super nice and walked me through everything right on the phone. good luck.
