Replacing the map.png in the mod can cause really bad problems. First, the whole world generation is based on the file and if you use a random other image, you will probably end up with ocean only. And if the new image has different sizes, it can be that the LOTR menu crashes.

I think, crashes while opening the LOTR menu are usually caused because your graphics have problems with the huge image size.
