jqueryui.com 500 Internal Server Error

i have a problem with the theme switcher tool :
http://jqueryui.com/themeroller/themeswitchertool/

so i try the url in my browser and get the :

500 Internal Server Error

all the jqueryui.com have the same error.

There is no way to have a functional download of the theme switcher tool and don't be dependent of the online tool ?

Thanks for the look.

Best regards.
