ok fixed the problem, apparently it is becos I (think I) got two soundcards installed. When I set in the audio-tab in xp under midi "microsoft wavetable synth' it works, while if I use the "E-DSP Midi port [9000]" from my producing soundcard it doesn't.

wow, it works when I set it to adlib. weird. where do I set the os midi volume in windows xp?

Hey guys, I have exactly the same problem - but I tried already 3 different versions including the one on the website here. No music :( . And sometimes the audio-sounds are missing, for example sometimes I can hear a laser being shot, sometimes not. crap :x . music is turned on in the menu. Anybody ...
