If you play a midi file with WMP or some other midi player (like Van Basco), do you get midi playback? If so, I think Windows can find your default midi output device, but BIAB just doesn't know about it. In Van Basco (and a million other midi players) you van view the list of midi output devices, and select one. My current and previous computers all showed the Microsoft GS Wavetable Synth and/or Microsoft Midimapper without me having to do anything. As Guitarhacker said, not the best, but that's not the point here.

My current computer is W7. I don't see that you you stated your OS. What is it? That may be significant.
