Matt - Did you double check the "Communication Settings"? That one bit me more than once. TunerStudio and my laptop would find my iphone's bluetooth and try to connect to that instead of the usb cable to the MS. This is what mine looks like now. This is on a macbook. Your Com Port settings are likely different if you use a Windows laptop.

Yep tried that many times, I have this cable and would try to unplug it and plug it back in which would help it work before. Exit out of the the program and go back in and everything, every time I ran a test port it wouldn't find my com3 I believe it is.
