CoD4 crashing

[ALLI]

iw3mp.exe error a couple of mins into the game.

I've tried going back to windows sound drivers instead of the realtek. i've tried plugging in a mic. i've tried re-installing.

still getting the error and im losing patience.

anyone? google seems to throw the same errors up.

Was playing fine until I installed the Realtek drivers. Have since uninstalled them but the error keeps buggin.
