I've had problems with that every once in a while on microstudio that would occur on one computer but no other. If you check your event viewer reports I think you'll find it a problem with either dot net (I can't remember the official name for it) or a dll file. Nothing I tried would make it go away. At some point, after a Windows update session i think, the problem went away on it's own.
I dont have extra soundcards at home but I'll try and check at my gig tomorrow.
