Need Corvette M6 File

I just Converted a 94 Corvette A4, to a M6, When I put in a Camaro M6 file, the car won't run and I can't read the computer, I have to pull out the computer and put it in a different car to put the A4 program back in, then the car will run. any thoughts on this? Does anyone have a Corvette M6 File they could e-mail me.

Thanks
Brian
