Call of Duty 4 Multiplayer Problems "iw3mp.exe has stopped working"

I just bought and installed Call of Duty 4 earlier today on my PC. After playing through a few of the single player missions, I decided to test the multiplayer to see if it was all it cracked up to be.

However, the moment I opened the multiplayer section of the game it crashed (it didn't even reach the title screen!). It then gave me the message "iw3mp.exe has stopped working". I tried running the game in safe mode: no dice.

Please help! :'(

I already tried both lol

Wow haha the microphone thing worked

Thanks! Why is that though?

That is so weird!! I always had a mic plugged in my pc, then one day i unplugged it by accident and my multiplayer stopped working!! I read this forum and the game started to work again!!

That is such a weird bug!

THx DDX2!!

I found I had the same issue with the onboard sound and COD4 in multiplayer. The issue is well known on the COD4 tech boards.

I took the long-term a bit more expensive route, and bought a Soundblaster X-Fi Platnum, and my problem immediately went away.

somting happend to mine too it just wont work . so i went and bought it on xbox!declan999
