Sheet Cam Crashes

I’m having a new problem this morning.
When I run the post processor or simulation sheet cam shuts down. no errors or anything just closes.
linux tng version 32 bit 6.1.50
post processor CandCNCPlasmaLLCNC-rev24D
not sure whats different, computer updated this morning.
should I try a reinstall?
and if so will I lose my licence info and settings?

Never Mind.
I reinstalled and that seems to have fixed it.
