Another MapMaker problem requiring help.

[Hallucination]

Attention anyone skilled with maps. Recently a friend of mine, Twoface, made me a heightmap. Everything seemed fine- It was 513 x 513, Grayscale, and a .png image.
However, when put it in Map Maker, it gives that famous "FeralHeart.exe has stopped working."
Anyone know why, or how to fix it?
Thank you in advance.

Try lessening some detail or making it 512 x 512 instead.
Hope this helps.

Did they create it with more than one layer at any point whilst they were making it? This'll cause it to crash. Even if they have created a layer then deleted it, it'll still crash.

If that's not the problem, something that usually works for me if a height map doesn't work is to copy and paste your file over the 'watermill.png' in your terrains folder then save it. Hope I helped. ^^
