Mango soundtracks xp12

[diyceejay]

So I've bought and installed soundpacks for both the ixeg 737 and ejets for XP12 They install correctly and sound great.

But then they are never there when I restart xplane and I then install them again while xp is running when they work.

I have skunkcrafts installed and wonder if this is the add-on that maybe causing it to disappear.

Has anybody else had this problem and know a fix/work around?
