If MIDI files are not associated with some app they will not strip. For instance if you happen to uninstall a media player or host that is your computers MIDI player and the association table does not reset back to wmplayer (default MIDI player), STMNO will fail to see this.
To temporarily fix this you just have to associate MIDI files with some other programs (preferably wmplayer). If for some crazy reason you really need this version pm me and I will send you a patch that fixes it. My suggestion is to just wait for the next version.
The newer (and much better) version will automatically fix this issue. It also no longer uses MidiDsm (and eventually MIDIFILE.DLL GENMIDI.DLL) as its backbone (had to learn somehow
