If you saved tracks as .trk ( after playing mission ) then you are toast , they won't play ,
they are gone with each different game version install .
If you saved track as .ntrk ( before playing mission ) then you can play them with any different
game install including the very first IL-2 Sturmovik game release as long as tracks are saved as .ntrk .
