Nope, no change. I figure there is sumtin wrong with it detecting the style.css since in the source it appears to be using the style.css from the default theme:
<link rel="stylesheet" type="text/css" href="http://www.null-coders.com/forum/Themes/default/style.css?b21" />
It is also the same for images.
Edit: It seems that I have gotten it to work, I am not completely sure how I did it, I changed the theme from a different screen this time and now it works. I will post more information if I can figure out what the problem was.
