Need help with a few things..I'm new to the movies

Kris wrote me an E-Mail:

I can't seem to post again to the topic. I don't know why this is. But I am hoping this will come through. I am trying to copy/paste all the costumes into this email (there are 6 total) but it will not let me. If I had to pick one to try I would try the Chewbacca costume .

This costume is one of the costumes which has its own category and is not added to an existing category. Now I can see your problem why this doesn't work. It's your first costume mod and you haven't installed any other costumes in an own category before. So you're missing this file: www.mediafire.com/download/s1q2re88kybxt2d/category.ini . This file must be modified when this is not your first costume - that's why the modder left it away so you don't make older costume mods unusable.
After you downloaded the file it has to be installed in the folder "costume".
After installing, a new category should be shown at your costumes. It's the category "new costume" and there you will find the Chewbacca costume.
You can also create an own category (eg.: Star Wars) if you would like to have the costume in another category but one step after the other. First you should try if this works now.
