WON'T START

[mightyepp]

The Hummer will not start. I tried installing the Diablo tuner. The backup for the tuner worked, then I tried to install the Diablo package and an error came up saying "illegal tune" or something along those lines. I tried reloading the factory tune off the Diablo and it keeps stoping and saying the same message. And now the vehicle will not start. I tried to jump start it, but the battery seems fine. I feel that my car locked me out from starting it. How to I fix this or do I have to tow to a dealer?
