I'm going to put in a support ticket but thought I would ask if this was something anyone has seen. I have seen this happen 4 times now and unfortunately it happened 3 times tonight. I'm on the latest version 4.4.4 and even stopped and rebooted my laptop to make sure nothing else was sucking up resources. I finally got things corrected and the car pulled like a raped ape on 2nd and 3rd gear pulls with great shifts and each time, the scanner froze.
