Everytime i open crysis, the game will run fine but if i go into the menus and say change keyboard or graphics setting and when i click accept it will lock up and send me to windows. The games itself runs it just wont let me mess with the settings. I tried to download the patch but it didnt work i uninstalled and gonna reinstall it soon. I am running on Windows 7 64 bit.
My system specs
AMD Phenom II X4 955 Processor 3.20ghz
4gb ddr3 ram
ATI Radeon 4870 1gb graphics card
