Bloody STYLESHEET Problem… Please Help!

Hey,
I’ve got kinda a really werid problem, made a basic site, index.php is linked fine with style.css but for some reason WP is not pulling any div id and class attributes out of the CSS (width, margin, border) but it is useing things like Theme Name and the other comments. When i take a look with Firebug, it tell me that the requested url /wp-content/themes/fontrock/style.css was not found on the server. I really want to keep on following the WordPress for Designers tutorials on http://blog.themeforest.net but i cant get any where.

Anyone got any idea?

Cheers,
Sam Rockwell
