I just registered on this forum because i am having a problem, si am using a VX-1000, everything worked perfectly.
I redo my hat led's configuration, with more precise dimension, so in FreeTrack i wanted to reset my setting to do all new setting with my 3 point hat adjusted, and once i clicked in Global Tab the Reinitialize Cinfig File, an kinda error window appeared, and i clicked yes too fast and didnt read, and right after resetting, FreeTrack started acting weird, i ended up having the same problem as eitai2001, see his pictures

Seing myself in the window as reg. cam view instead of infra red view like before, and a weird gray line appeared on the bottom of the cam view exactly like yours, i uninstalled Free Track, rebooted, re-install, and noting, still does that, i even re-uninustalled, install version 2.1, and wasn't better, was working, but my head was upside down in the movement window with the skull head, i even re-installed webCam Driver.
Then on another forum someone replied to someone'S problem by uninstalling FreeTrack and delet the folder still there in ProgramFiles, then re-installed Free Tracker 2.2, rebooted, then was working ok, so i continued my settings, adjusting led, unpluged my hat to ix leg, then another odd bugg started, the cam view started to boost light, so i could see myselg in red/black in the view, like there was no Filter in front of the cam. I again uninstal, re-install and this time, the normal webcam view came once more. Anyone has any idea, i'm kinda pissed, it was working just fine before.
