F9 used to bring up my tire temps but stopped working. I've tried everything including reinstall. Anyone have a suggestion?

type in /press f9.

If the tyre temp comes up then your F9 key is buggared.
If it doesn't then LFS is buggared

The presence of other menus will disable the F key menus. Such as connections list (n), or the live suspension display (Shift L).

thank you, I'll give it a try

TrackIR captured my keys. Turned it off and problem solved.
