is your map on a 513x513 scale? map maker will crash if it's bigger/smaller than that.

also, what program are you using?

Make sure that you flatten your height map image. Merge all layers and then right click and hit "Flatten Image".

Make sure it's in grey-scale also. If it's in RGB it will crash the game.
