and if i click yes or no it says iw3mp.exe has stopped working please help

[imported_Tren]

try starting up single player and then switching to multi player.

If that doesn't work try restarting your computer.\

If that doesn't work, try to get a iw3mp.exe file from another person and replace your broken one.

If that doesn't work, reinstall COD4...but make sure you have a copy of the file or whatever that stores your rank data. (Not sure where that is on your comp though)

Just found the fix for it yesterday and I already posted it in another thread here.

I had this too and I found a fix for it. It sounds funny but it works. You have to plug in your microphone into your sound card and it'll work. Try it out.

Firippur - Do you have a USB mic? I do not have a USB mic and plugging it in does not work for me.

I have exactly same problem that is described in this thread and so many others.

My system is getting aged but is capable of playing this. I was able to play for a few days but I could not connect to all the servers so I tried a reinstall and nothing works now.

Here is my system specs:
