Installed user board in RSX ECU, clicked OK when it asked if I wanted to lock it to the ECU.
Uploaded my tune to the ECU.
Ran the engine, watched a little live mapping, then shut down to work on other things.
Restarted engine, connected to KTuner, now I just get a popup saying board is already locked to another ECU - WTF?????

Or

Please advise.
