Input string was not in a correct format and item with the same key has already been added errors.

I had figured out a way to get Simitone to work with downloads and hacks but it's still very picky when it comes to cc and custom animations and crashes on the loading screen and gave me an item with the same key has already been added error and in CAS an Input string was not in a correct format while it was trying to load the skins up and the crash logs weren't very specific about what had caused the crash unlike the mod crash log which had explained which files had made the program crash so it's difficult to fix especially since I have lots of them.
