DSOUND.dll problems!! - Need help guys.

[MonkeyMan]

Bugger. All of a sudden everytime I try to open itunes I keep getting the following message : -

"The application or DLL C:\WINDOWS\system32\DSOUND.dll is not a valid windows image. Please check this against your installation diskette."

I have to use taskmanager to end the itunes task to get the window to shut. Very dodgy.

In fact I just tried to open Windows Media Player - it does open but wont play any audio files. Winamp didn't want to at first but then I changed the output from the DirectSound Output to WaveOut output and it seem to play files ok.

Thinking along the lines of Direct X issues - I downloaded the latest version (Direct X 9 c I believe) and this still hasn't cured it. The one thing that I noticed when trying to source the problem via the Direct X troubleshooting programme is that the DSOUND.dll in question did not have any driver version number, date or anything next to it. All of the other dll's did have.

Urgent help needed folks...
