I apologize if this issue has been brought up in the past. But I can't seem to find it anywhere. The issue I am having is that no matter if I try to read or program to the ECM or TCM, either right when I start or during the flash it will give me a no data received error about 19 out of every 20 times. So eventually I can get it. I have made sure all drivers, firmware, and software is up to date. and all cables are snug. It wasn't bad at first but recently its been getting worse and the last time I loaded a new calibration it crashed mid-programing and when I went to restart it said my VIN wasn't licensed so I had to use my second one. I am little worried it will do that again and I'm out of licenses. If anyone has had this problem or could shed some light on the situation, your help is much appreciated.
