The game doesn't recognize the TrackIR
The green LED on the right of the camera that indicates a compatable game is running is not lit and the device will not function with the game.
I have tried updating the game list in the TIR and checking the files of the game.
I am using a TrackIR5 and running Vista 64-bit

Let's try some installation troubleshooting:

Unplug your camera, and uninstall the TrackIR software.
Download a new copy of the latest version of the TrackIR software, and save it to your desktop (note: do not run from the downloader).
Right click on the installer, and select "Run as administrator" (even if your account is an administrator) Finish the installation as normal, plug in your camera, and verify that drivers are properly installed via the device manager.
Run the software, and see if it works properly.

Additionally, you may want to try running both the TrackIR software and A-10 by right clicking and selecting "Run as administrator" as well.

That did the trick!
I had tried re-installing the software but didn't unplug the camera.
Now it works fine

thanks
