Feral Heart

Can someone please help? I downloaded a map that has so many files and so I exported them, and now when I click on the FeralHeart icon the game crashes. It keeps on saying "feralheart .exe has stopped working" and then I have to close it so I can't log in. I tried going to particles folder and there's no _01s or _02s. I also tried shutting down and it still pops up. And I don't want to reinstall FH cause then I'd lose all my maps and such. HELP!
