Can't get .midi files to play using PlayMusic

Can anyone else get this code snippet to work? of course, you will have to substitute your own .mid file

chnTitle=PlayMusic("Title.mid")
If chnTitle = 0 Then RuntimeError("file not loaded")
WaitKey()
End

I can't get it to work and keep getting "file not loaded" errors. The .mid file is in the same directory as the executable.
