It would appear that free track hasn't been updated since November 22, 2008 so it's very unlikely you'll get any support from the programmers themselves.
They do have some support forums
HERE. Maybe you'll have better luck with them.
The last time I tried to use freetrack, I was running XP Pro 32bit, and the software crashed on me on a regular basis.. at least once an hour. This, and the fact that I never could get it to work right when i didn't crash (I blame that on the ancient webcam I was trying to use more than anything) persuaded me to purchases TrackIR - of which I have had almost no problems with.
