I think this would probably go better in the game help board. A mod will move it for ya soon!
As for your issue, usally when a texture is just colorless and white that means your game is looking for a texture that doesnt exist. Make sure you have followed the directions, and pasted all the stuff in there in the correct folder. Is your problem a problem with your markings or the FH canine and feline textures? If you let me know this, it can help solve your issue a bit better and let you know where they go. ^^
