My personal advice, export model with skins, bones but without animations into MilkShape and from it into MED, after that export it again, but with animations and directly from FragMotion into MED. Export animation frames (into .txt via MED) from it, and then import and replace animations in the model which was imported from MilkShape. That helps a lot, cause sometimes animations quality suffers after you import it from MilkShape. Good luck.
