JQuery UI theme roller not generating images

JQuery UI theme roller not generating images

Hi,
I'm trying to roll a jQueryUI theme and I'm having some trouble with it. After I download the theme the css file seems to b mising most of the "Images and States" section and there is no css/images directory.
As a result, when I include any jquery widgets they are not styled.
I've downloaded several custom jQueryUI themes in the past without issue, so I sort of feel like I know what I'm doing.
Is the theme roller broken? Or am I doing something wrong?
