What do you play on? Do you play on a mac or Windows?
I also suggest changing your rendering system. If you have OpenGL, you can go into the FeralHeart folder and open ogre.cfg. Next, in the first line change it to Direct3D9. Do not change the line below it, since that causes a crash. You can do the same thing with Direct3D9, but the opposite. Hopefully this can help you out a bit.
