I didn't make it!
I have the same problem. I bought a new computer a couple days ago after my old one literraly died, this one so happens to have Vista, I tried changing mssmp3.asi to a bak, didn't work. So can somone help us?
Have you updated your video drivers and Vista?
I have just tried the mssmp3 thing but didnt work all my drivers a right up to date
What version of Vista are you using, have you turned User Account Control off?
32 bit and i have the only acount so im the administrator
Administrator or not, turn of UAC.
It causes problems by forcing things to save in a Virtual Store rather than the root directory.
Ok i have turned UAC of but it still does not work
Well, I don't know what else to suggest so I googled it.
Many people are having an issue when launching the multiplayer portion of Call of Duty 4.
Tips: Reinstall the game Update your Drivers
There are some issues running CoD 4 Multiplayer on some onboard sound cards. Users with RealTek(TM) onboard sound cards and Windows(R) Vista will need to use Microsoft Audio Drivers 6.0, which can be found at Microsoft Corporation and/or COD4 Windows Vista Audio Drivers Fix. Users with Sigmatel® onboard sound cards need to install all Windows® Vista updates, and the latest Sigmatel drivers from Dell.com.
If you are running the game from a secondary partition, download the latest BIOS updates from your motherboard manufacturer in addition to following the above instructions.
A fix will be posted here once Activision/Infinity Ward releases more info on this error.
