I am out of my element and over my head with this kind of stuff, but I am determined to do it myself. I am attempting to do a calibration flash on my truck. When I use my laptop and Tune V7.5, I get "your flashscan interface cable is not yet licensed to flash this ECM." I think I have done everything I am supposed to to license it.

I also tried to do it only using the flashscan V2 after following a writeup to set it up with V8 scan and tune. I get error $0502: script file not found.

What am I missing or possibly doing incorrectly? Thanks for your help.
