You can, but I'm not sure about how accurate it is when using a mic as I've never done it that way.
All you need to do is change the RIG INPUT to MIC, right now you probably have it on GUITAR.
Also 2.0.1 is the latest Firmware. 1.1.6 is the latest DRIVER version for Windows
You also mentioned you are on 10.3.6, there is an update available for Pro Tools 10.3.7
