I have my wii mote connected via blue solil as a HID.
Does it also show a name like "Nintendo RVL-CNT-01"?
I tried freetrack also with a wii-remote.First with bluesoleil software and later with Toshiba bluetoot stack.But I stopped with it.
I had a lot of connecting problems, empty batteries of the wii-remote.For me it worked better with a normal webcam.
Other bluetooth devices seemed to interfere with the connecting of the wii-remote and my pc.
If you wish to continue with your wii-remote, you can try to turn of UAC(user account control) and start everything with admin-rights.Check also if you bluetooth device is compatible wit a wii-remote.

You know that only the latest version of freetrack works with a wii-remote?
