Predator won't work

[ThrowFar]

So I got my predator today and everything was going fine, I downloaded everything from the website and was set to go. I hook up my predator through the usb that came with and I "callibrate". Well after it tells me i'm through I go to my car and plug it in but everytime "Invalid calibration file(1)" pops up. Any information on whats going on mike? Thanks alot
