'Invalid directory' problem when loading .nif files

[lpzimm]

I'm trying to modify the servant - Eyja - to be a Khajiit. When I play the game, the tail is super stretched and stuff. I did some searching and found that this was because I was using the normal human skeleton instead of skeletonbeast. So I tried to load the skeletonbeast file by using a BSA extractor, but whenever I use it, it tells me 'Invalid Directory.' It's in my data folder, and I've tried launching as an administrator. I can't see any of the .bsa folders either. Please help!

Edit -- Figured it out! I had to rename the directory that had it to 'Meshes'
