Try downloading it again. Then, export it to C: >>> Feralheart >> media > textures. Make sure you click REPLACE...! That's very important. Otherwise, it won't work. ^^
I really don't know. o-o Try exporting them to your desktop, then delete all of the fur textures in the textures folder. Then move the IT textures in C: >>> Feralheart >> media > textures.
Also, make sure they are named the same as the original textures. Maybe they are already in the textures folder, they aren't just named the same as the originals. (If that makes sense.)
Hope that helps! o^o
