F-18C Head Tracking Doesn't Work

[NMC 6]

Hello All, long time lurker, first time poster. I'm using Opentrack with a Grass Monkey Puck , which works in every DCS aircraft I have except the F-18C. TF-51, Su-25T, all FC3 jets and HB F-14 all work, but nothing for the Hornet. I'm guessing there's a setting that I'm overlooking but cannot find it. Any help would be greatly appreciated!

Try to reset the column for TrackIR in the control settings to default.
Cheers!

Had to load a profile first, but then that did the trick - thanks very much!
