BGMC 17 I have a song on LMMS I need help with exporting

I made a song for my blender game the song’s on “LMMS” I need help exporting it to a sound file blender can run in game. I’ve tried but I’m too new to the software to get it to work.
The song’s done and I think it loops well and would be good for night time or something ect.
here’s the .mmpz LMMS file http://www.mediafire.com/download/tv2u3pdbw3p1c59/JoshuaJaysGameMusic.mmpz

Download the Audacity and convert to wav or ogg , you may need LAME plugin for Audacity

The .mmpz is the LMMS project file. Open it in LMMS and export (File -> Export) to either .wav or .ogg, which are audio files.

Edit: By the way, Audacity will not open .mmpz

I’ve tryed exporting it in LMMS but the program brakes, that’s why I was hoping someone that has done it before would give it a shot. But it’s too late now with the BGMC 17 over.
