Hi,
There seems to be a conflict between TrackIR 5 and the FS2Crew gauges used in the FS9 ATR edition. If TrackIR is loaded then FS says that a number of gauges cannot be loaded, but if I start without TrackIR, and only run it after the aircraft is initialised then everything works fine. Seeing as it is possible to workaround it's not a major issue, but I wondered if this might be something simple to fix in your next update?
Cheers,
Mark
