They changed too much in the 'remastered' DKS - layouts of flying fortresses, positions of items, NPCs and quests etc. So it's not just a matter of a save game translator, the problem is there are logically inconsistent states between the two games.
If you want to continue your game from ED, you need to get the stand-alone FoV expansion rather than the remastered DKS, but I guess it's too late now. FoV has the same contents regardless of which version you play, but there are still fundamental differences in the game engine to allow compatibility with ED saves vs DKS saves, so even at the FoV stage, saves apparently aren't compatible.
