Hurm... Well, do you have any meshes or maps in your files? Or did you download anything from mediafire into your Feral Heart folders?
If so, I'd recommend you deleting them. But, copy and paste them into a folder which you can remember, [That won't crash any other game] and leave it in there. If the problem doesn't fix itself, then you can put the files back.
Also, sometimes it could be your settings. What settings do you have on? You know when that white pop uo box somes if your Feral heart crashes or you first download it. It has the picture of a wolf and lion.
I hope this helps!
