Feral Heart

I was having troubles with my camera that i couldn't fix, so my friend suggested i uninstalled it. Keep in mind my game was fast and working properly at this time. I uninstalled it, and reinstalled it. It goes to a gray screen with a pop-up saying, "FeralHeart.exe has stopped working" I've tried reinstalling 5 times. If it worked before, why can't it work now? I've tried the particles and the ogre.cfg (whatever its called) and i can't open it. Please help?
