Height Map wont Work

[TiredMedic]

Whenever I get on FeralHeart and go to map-maker, I load my map, Pridelands(name is changed for privacy) and click on the maps tab. The minute I type in my height map name, it closes off and says - "Feral heart is not responding" When I enter my Terrain mask name, it works fine. What am I doing wrong?

Make sure your height map is in greyscale and same size on both sides. Example: 513x513

Now I see... Thanks!

EDIT: I made it the same size, yet it still closes when I try to enter the Height map file. Having a flat map would really suck..

@Michelle: Ja, ich sprech Deutsch xD
@Breanna: Maybe try switching your color mode to RGB and then back to Grayscale. And about the One-Layer-Rule: It won't help if you flatten your image, you know. It has to always have been one layer.
