Oh my gosh!!!!!  I think I've found the problem. There was a space at the end of the "Anime Ponytail Hair " folder, so I think that's what was causing your problem. Many people like me don't notice the problem because our zip/unzip software ignores spaces at the end. But, I'm guessing your software doesn't like it. 

I've fixed the DS zip, but since you only need those two files for the right ponytail, I'm going to SiteMail you a link to download just those two files.  Or you can re-download the entire DS zip file, if you prefer.

My apologies for not catching that earlier, it was such a tiny little space to try to see. I'm really hoping that solves your problem. Please let me know if it doesn't work for you.
