TrackIR not registering

[Myst1cPrun3]

I've got a new PC and installed GPB on it, and got the latest TrackIR software, and it doesn't seem to register that there's a game running, despite the fact that I've got all the relevant settings selected in the game. Is there a file to edit, or have I missed something else

Resolved: Appears I have to launch GBP in VR mode to get it to work. Didn't have to do that previously but it works so I'm not complaining
