It sounds like a problem much larger than ai war; it can't mess up the zone on your entire computer, but you could get errors like this if sound on your entire computer is messed up.

My best guess would be that directx 9.0c got messed up and needs to be reinstalled -- we have an installer for that on the prerequisites sticky topic if you like.

If that's not it, then it's probably either a driver got messed up, or actual failing hardware. You probably have some error messages in your windows event log about the error unrelated to ai war -- either a directx problem, or a device failing to start.

Hope that helps!
