Why isnt feral-heart the game not working on my other computer?

I play feral-heart the game and i don't get why it's not working. When i try to get into the game, it tells me something about OgreGLTexture.cpp, yea something like that. Why is it doing that? It also said create surface texture and it said some website that doesn't even work. Im not sure what to do to play my game. Can you help me?
