Vista - Call of Duty 4 will not work on my comp!

Dose anyone know what I can do to make Call of Duty 4 run on my system? I am running Vista x64 on a Skulltrail system w/ 2 Quad Core Xeon's at 2.5 Ghz, 2 en8800 gt's in sli, 8gb of ram...

I ran the game fine on my XP install, but since I moved to vista I haven't gotten it to work. I have tried: running as an administrator, changing the folder permissions for the install directory, running in safe mode, running in compadibility mode, and that's all I can remember at the moment... needless to say I'm quite furstrated at this point.

The error I get is "iw3mp.exe has stoped working"... Same thing for single-player exept "sp". I am really only interested in multiplayer though...

If anyone can help it would be greatly appreciated. Please provide helpfull comments as however, "Go back to running XP" ,for example, isn't...

Thanks,

Have you updated the game with the latest patches.

Yes, and I have tried running the game incrementally throughout the patching process (it gives me the same error for every patch).

Go into the control panel then in sounds and click on the recording tab and right click in a blank are and make sure show disable devices and then enable recording mix and ok everything and see if it will run.

I had that same exact problem but for the life of me I can't remember what I did to fix it.

I tired the sound thing... didn't work ... it was set that way already... How is that supposed to help?

It was one of the work around to get the multiplayer to work.

Ah, well it didn't work unfortunately... what else should I try?

Have you tried doing a clean install of COD4 and deleting all files and folders that pertain to COD4 on your computer and also deleting the registry keys.

Everything minus the Registry Keys... *sigh... guess I'll start downloading the patches again...
