KF KF crash on start up (general protection fault)

I tried rebooting my computer and verifying the file cache in Steam but still crashes. Worked fine the other day and I haven't made any changes since then. I'm going to try re-installing and will report back.



In the meantime, here's the error message:

General protection fault!
