I just got a Track Ir 4, actually for my Dad, I have a 3 but without Vector Expansion. I plugged in the 4 turned on the TiR software and it recognised it and the Vector Expansion was activated, so far so good, checked that the 6dof was working in profiler and fired up IL-2 in the 4.09b6dof mode and when it gets to 100% it crashes to the desktop? It works without the 6dof just fine but, all my view keys act like they've been re-assigned, hit F2 I get a camera on the ground instead of the view of my plane and I can't get the cockpit view back, doesn't seem to be a stuck ctrl key or anything wrong with my keyboard so I'm baffled as to what is causing the problem, I'm not computer challenged but my Dad is and if I can't figure it out he never will, anyone know a solution? I didn't reinstall the software so that's my next course of action. I would appreciate any input.
