Reply to MF Problem, One Button to Rule them All???

So I got my MF in today and was messing around with it, left to go eat, came back and now when I press the lowest right hand button the whole bottom two rows light up. They also don't send MIDI notes and don't register in TSP2. Is there a way to remedy this? I've already flashed it with what I believe to be the newest firmware, I've gone into menu mode, but I can't quit menu mode, the exit button, which is the same button as the one that lights all of the other ones up (I believe it's related to the same problem) and it's kind of frustrating me. I've done everything that I have found possible, but its just not working. Any ideas?
