Okay, I uninstalled FH and re-installed.
It wouldn't let me download DirectX; it said something to go check my Windows files or something.
I was going to check if it worked anyway, but when I put in the name of my height map it couldn't find it! What?? I think it's because it's not in my C:>Feralheart files because I uninstalled it, but I don't know where my copy of the height map is. I'll try my pictures and edit this if I can find it. If not I can go get it from deviantART cause I posted it on there. (Never thought posting something would save me so much trouble o-o)
