Call of Duty: World at War PC Error! Help!

I bought CoD5 about a week ago and it ran just fine on my PC (which runs Vista) then suddenly two days ago when I tried to start it up again it went to a black screen, stopped responding, and then open up and initialization box that says: "Error During Initialization: Unhandled Exception Caught". I've tried to look up solutions to this including: uninstalling and re-installing, changing my speaker settings to (24 bit, 48000 Hz (Studio Quality)) which had no effect because my speakers were already set to this, and deleting the Treyarch.Bik file from the video folder of the game, Nothing seems to be working! Anyone have any actual solutions to this problem?

Anyone?

Nevermind. I fixed it myself.

If anyone else has the same issue try plugging in a headset like you had to in the CoD4 multiplayer. It worked for me.
