Follow the instructions in the setup.txt file - you are missing the reference to the reset.css file, or it isn't loading correctly. If firebug/chrome inspector doesn't show the browser trying (and failing) to load this file, you are missing the line - if it does show it, look at the error message to see how to resolve this issue.
