Just had a customer come and leave.
2007 Colorado with the 3.7 I5 motor. Read his file no problem, licensed single vehicle only, did my editing. Went to flash the first revision and the flash message box stalled at #2 Validating License and read "Write Not Allowed" in red lettering. I can reread the PCM and not have it ask for licensing but I can't flash it with either the stock or the revised file.
Pulled PCM fuse for a minute, no change. Don't believe the issue is his vehicle, doesn't get to the communicating with vehicle stage.
I installed the latest beta this morning after the issue. No change. I think I last updated in Feb.
I've emailed support but wanted ask here as well if this has happened to anyone?
