When I press the start button in the freetrack software, I get the message "Are you sure you want to exit the program?" When I press no, it stays in the program, but nothing happens. Can't see the head tracker lights. It also seems that the camera software is interfering with the program. This is the first time I use freetrack, so maybe someobne can help set it up properly. I tried to follow the handbook, but some of the stuff is written in french or so, I don't know. Maybe it is easyer to buy TrackIR. I use the logitech c250 webcam and use the trackIR pro clip as head tracker. Please someone help me out here.
