ThemeRoller not giving me correct markup

ThemeRoller not giving me correct markup

I created a custom theme using the ThemeRoller.  I downloaded the entire package and wired it up just like it shows in the example.

All of my dialog boxes (the only thing I use) are formatted incorrectly. Everything is completely left-justified, the "close" icon for the titlebar is shifted completely to the left and there is no background for the buttons at the bottom.

EVERYTHING is wired up just as it was in the example, to include the CSS file. I'm using jQuery 1.4.2 and ui 1.8.4.

Why would something like this happen? Any ideas?
