Crud I gotta redownload FeralHeart..-facedesk-
I'm not sure why it'd be crashing your game, so long as you installed it correctly and weren't having a rendering engine issue (you can change the rendering engine either through the in-game options, the launcher splash screen, or ogre.cfg in C:\FeralHeart). Maybe it was just the game itself? Anyways, I apologise for the inconvenience - and as the installation instructions say, it's always good to have a backup of your FeralHeart folder just in case. :3
