i feel like an *****. when i was going through Add/Remove programs (i have windows XP btw) i accidently deleted something that made my sound stop working... i have a feeling that it was some audio software but im not sure. when i click on program say iTunes... it tells me this : " iTunes has detected a problem with your audio configuration. Audio/Vidro playbak may not operate properly. so basically i accidently "deleted my sound" i dont know hwere to start or what to do. if anyone can help me that would be great.
