I was just on the conedodgers server, i was on the car setup/garage screen and each time somebody left the pits an error came up in the chat saying

GetPlateHandle failed

Any ideas what went wrong? was a full race at the time, maybe something to do with that?

I don't know if you could have been out of texture memory.

If it's reproducable when you restart LFS, you could try using lower texture resolution.

Options... Graphics... Full size textures : NO

Alternatively, run in a lower screen resolution, or switch off VSYNC, or use 16 bit Z buffer.
If any of those or similar memory saving measures fixes it then you probably ran out of video card memory.
Or maybe your computer just needed to be restarted to clean up the memory.

EDIT : I've also added it to my bug sheet to check if a full grid could cause this without running out of memory.

I also had the "GetPlateHandle failed" message twice. Happend both times when I entered a full server.
But it never happend again till today or was reproducable.

Just to help scawen, i was using compressed skins and no v-sync. though i think i had frame rate capped to 62fps if it helps.
