Motion track not working DK-1

I've got the OUDK from the developer area installed (0.2.4) but it won't track the movement of the headset.

I changed the engine.ini so it does the stereo, but in full-screne it won't work and just blackscreen crashes when i use Play On PC.




suggestion?

my Rig:

Geforce 970
Intel I7 960 (3.2ghz Quad)
24 GB DDR 3 Corsair Gaming Ram

Resolution: 1920x1080 (If that's the issue, I know resolution fucks things over sometimes for some weird reason)
