Map maker crashing

[Coyot32014]

Ok so everytime I try to go to map maker it says FeralHeart has stopped working.Everything else works.It didn't start doing this until today when all these changes,or whatever has been happening,have been going on.Is it because of those changes?Or is something else wrong?I just need to know because I was working on a map and it's about half way finished :B

Back up your "terrains" and "object" folders, but delete your entire Feral Heart folder and reinstall. Once reinstall, add back terrains and objects, and in theory, it should be fixed
