OK, there is no C47 Mod. It's a files thing. a) Do you have soundmod installled as required? If not install it and try again. b) D/l the skytrain exe folder from AAA, extract it to desktop (as I already told you). You'll find a 3do file (containing B25j cockpict, etc.) and 5 files with numbers. Go to your files folder, find THOSE files and disable them.
If you want a fresh start, you can decide whether you will follow the "big packs" way or the individual installation. I have a SAS-activated game, with renewable buttons which allows for individual Mod installations and works fine (I am an offliner).
Good luck
