I am trying to reflash my 2015 seirra. I read out the ECM and TCM only. When the read was finished I saved the file, made so adjustments and clicked write. I selected write calibration for both ECM and TCM and the window popped up for licensing the units. I had 6 credits on my account and clicked apply. No other error windows popped up so I clicked write and got a message saying unlicensed vehicle. I've flashed many E92s in the last few months and never had this issue.
Any suggestions?
