CTD at main menu

[CTD at main menu]

I wonder if thats the case on my end....and if reinstalling would help?

[CTD at main menu]

Hey fellas

Yeah im having an issue. I tried the ArmA 2 Demo first before I bought the retail version, the demo played real smooth with no issues. So I figure ok this is working well and its fun, so I'll buy it.

So I buy it and I cant even make it passed the main menu before I get a CTD, and if I just sit at the main menu it'll eventually CTD, plus anything I click also causes a CTD.

This is what im running

I've tried running the game in compatibility mode for windows xp and that didnt work, I DL'd the latest drivers and that didnt work.

So right now im just kinda stuck, any of you guys have a suggestion?

I played the demo well with no ctd's or anything yet for some reason I buy the retail game off steam and I cant even get past the main menu, everytime I click an option no matter which it is the game CTD's.....Good times.
