I see that we were talking at cross purposes; I had assumed that you were both talking about the midi linked to directly from this thread. I've looked at the DT midi file now, and the reason it won't play is because the music doesn't start until the 646th bar! I think this sort of error (this is not the only case) is due to the way the files are generated in the first place, but it would be the work of a few minutes only for someone with the appropriate password to fix it.
