Please help! Right jog wheel not working

Hello! I have a ddj400 that I JUST bought. My right jog wheel will not work. It doesn't scratch (I have vinyl mode enabled) when I try to search, the wheel does not want to move from the cue. I have tried midi shortcuts, I have tried a different USB port, I have it plugged in to a computer that supplies more than enough power. I have tried everything in the above mentioned. Please help me!!! I do not want to give up in mixing!!! Please help!!!
