[Plugin: Smart Archives Reloaded] Does not seem to load the CSS file (smart archives)

I am trying to include the smart archives on my blog. I get the list, html output looks ok, but somehow the CSS styles are working. So its not formated at all. Unfortunatly I am not a CSS guru. Does it matter for the archives style that it is nested within an another DIV?

I have tried to copy the dev.css file into the style.css file.
