    2001 chevy duramax

    Trying to take out vats and tune. It will read and allow me to make changes, but when I go to write it says unlicensed file and will not automatically read the vin. I can manually put in the vin.

    buy 2 credits and license it. maybe resync your mpvi if you already have credits.

    he has the credits.. it doesn't show the normal option to apply the credits to the vin because no vin is shown.. he sent me the upload and I tried also.. it comes up normal screen where you would apply 2 credits, unlimited or do not license.. it only shows do not lic… the truck previously had a handheld tuner on it.. he returned to stock and then struck wouldn't start.. now it scans and shows ecu with hpt but it wont show vin or allow to license it...
