Okay, thank you guys. FreeTrack kinda works now, but it seems to be resetting after every new start of the application.
@trooph: I would like to use OpenTrack if it's better working and still get updates. I already download it but don't really see what to do, to adjust it properly. Are there any instructions?
I managed to set Tracker to PointTracker 1.1, Protocol to freetrack 2.0 Enhanced and Filter to Accela. I even figured out how to get my three leds to be correctly appear. But how do I adjust the virtual head moving properly?
@Poneybirds: For some odd reasons it seemed to help, to remove the film. I'm not really sure how I managed to make it work.
Edit: I even managed to configure it properly by myself. If there any further informations, I still would like to read them. Thanks!
