Project Reality not working

So Project Reality has been working fine for me since I downloaded 1.0 last year. However, yesterday I experienced a major game crash that crashed my computer. It took an hour to get my computer to run again after a long time of "Repairing any issues with your computer" or something.

My computer is all fine but I went to play PR today and noticed that it says:



So I'm like okay then, and went to my "Options" section to find that the "Display" section is blank:



So I change it to my normal settings etc:




But I go to play and I still get the same error message? And when I go back to the options menu, the "Display Mode" bit is still blank? Could this be anything to do with the crash I had yesterday? Please help if possible! Thanks :-?


(P.S vinnila Bf2 works and so does any other mod)
