Well, running it as an Administrator didn't seem to work. Anyways, I normally only make feline presets now because whenever I make manes, they are blocky, and I don't normally put manes on my felines. I had decided to make a dog preset though, and the character had a mane. I made it, and when I put the texture on it it would be blocky in game. I had a friend tell me they had a code to fix it, and when the code didn't do anything to change it because it wasn't even, she sent me a new NotePad to replace it with. I replaced it, and from what I can remember before I messed with preset_6 was the last time I got into FeralHeart.
Hopefully I won't have to reinstall, as I have a lot of stuff I'd have to install again, I don't know how much this old computer can take!
