Can't see plane, or entire opening scene, mouse and keyboard don't work.

Anyone else have this error? I just installed Crysis last night after upgrading my comp. Specs: win7 32 bit, ati 5770, amd 945 3.0ghz quad core. My mouse and keyboard work in the menu, and in-game I can hit esc and it will bring me to the menu. Basically I start the game and in the opening scene there is no plane, no characters, and I can't move or look around. Strangely I can turn on night vision. any help?

Just opened steam and in downloaded an update that fixed the problem.
