Im tunning a car for a guy and I purchased just the two GM credits. Read the file, applied the credits to that file, rewrote the tune and saved the file. I go to rewrite calibration and begin the rewrite and it brings up the credit page saying I need to purchase two credits for a VCM enhancement, and of course the next option is 20 credits for unlimited tuning for gen 3 vehicles. Any ideas on what I can do to get this rewrite going? I know if the file didnt have credits applied to it I wouldnt be able to save. Please any help would be great!
