from activision support:
Set the Virtual memory to a fixed size. 1) Right-click on the My Computer icon and select Properties. 2) Click on the Performance tab and click the Virtual Memory button. 3) Select Let me specify my own virtual memory settings. 4) Set the minimum and maximum size to 600MB.
If you are still having problems then uninstall the game, delete the game folder, and then reinstall the game. Make sure that you do not install any third party maps/mods/skins of any type.
