Capacitive Touch Shield

I've been trying to get the Adafruit 12 x Capacitive Touch Shield up and running but they've not documented it well (IMHO). I can't even get their test example to work. I posted something on their forum, but my assumption is that this is a more active community. Has anyone had any luck getting this thing up and running? I'm specifically talking about the 12 X shield and not the breakout board which also uses the same mpr121 chip.

This guy:

I'm running Arduino 1.8.3 on a Due Rev 2.

Any help would be appreciated.
