All the themes work but Atahualpa Won't

I've tried several different themes. All the themes activate and are visible on the webpage. I have atahualpa intalled and it will activate so I can access the back of the theme to modify and use it but when I try to see it on the webpage I get a error 500 internal server error or a 404 error. I've tried everything from reinstalling the theme to reinstalling wp. Is there a known problem with this theme.
