"Game Data Only"

For PPC, i have a game, called MyGame.exe, and on Return-Key, i want the game should Restart. What do i do ?
Because neither works on PPC. Also i exported a TestGame.ged as GameDataOnly, placed its sprites in the data files and copied TestGame.ged along with MyGame.exe onto the PPC.
But on Return-key, i always get a black screen
am i doing something wrong ?
- On KeyDown

LoadGame("MyGame.ged") or LoadGame("MyGame.exe") ?
