Okay, so I find the my modded .iwd. I put back in the backup's and save it. I get out the modded .iwi skin and add and replace it with the original. I update the .iwd when WinRAR asks me if I want to. I drag my .iwd file into the folder with the modded iw_07.iwd and backup. I place it over it and move and replace it. I managed to get one skin to work, but some other skins do not.
