Have the "tracking on" the screen , it shows the three green things . 
When you "look up" does all three of those "things" stay on the tracking screen ? 
If not than that could be your problem . I use the hat clip myself ( not in this game , I like AH hat control better than trackir ) and had to bend the top of the clip ahead some to get it so that all "three green things" were on the tracking screen when I tiped my head up .
