Sequence of events today:
-Upgraded to v. 7.3 PR 10, but didn't update my .cal files
-Made some changes to my tune and flashed it onto my PCM fine
-Upgraded my cal files
-Went to reflash my PCM again and the PC locked up after erasing flash memory and when the status indicator was at 4 of 512 KB transferred
-Turned off ignition, restarted FlashScan, went to re-flash PCM, and now it says the PCM is no longer licensed!
Any idea what happened here? My truck won't start now and I don't want to relicense its PCM unnecessarily. Suggestions?
