In response to ButSam's original question, the program must be in the same directory as your SE4.EXE as dumbluck pointed out.

Next, to the problems with Savegame loadings, I know they definately work with passworded empires for simultaneous games...
just tested with turn-based and that works too

As for unpassworded empires I believe I have a solution.
it's actually a small problem with the SE4 command prompt I believe.
if you enter a single "space" character into the password box it should be able to load your games.
Of course, make sure you select the right savegame, enter your player number (most probably 1 if you're singleplayer or hosting) and then click the Load Saved Game button.

Apologies for the "spaces" in the player-number box, just select them and type numbers over them.

both of the above issues will be addressed in a new Version in a couple of weeks (when I get an hour to do it)

Hope this all helps.
