doesn't seem to work with my cam

Hello!
I've tried your program Хeoma.
I like the module-based principle of functioning very much.
However, for some reason it doesn't work right with my webcam Microsoft LifeCam HD-3000, while it does work just fine with some other, cheaper cams. I have a loading cam sign on screen though the light indicator shows that the cam is on.
And it works fine with other programs.
Any thoughts on how to fix it?
