gah..my fault was really stupid.
forgot to set the path to my css files correctly.

wrong way:

<link href="stylesheets/sIFR-screen.css" rel="stylesheet" type="text/css" media="screen" />
<link href="stylesheets/sIFR-print.css" rel="stylesheet" type="text/css" media="print" />

right way:

<link href="<?php echo get_template_directory_uri(); ?>/stylesheets/sIFR-screen.css" rel="stylesheet" type="text/css" media="screen" />
<link href="<?php echo get_template_directory_uri(); ?>/stylesheets/sIFR-print.css" rel="stylesheet" type="text/css" media="print" />

I have the exact same problem.
Investigating it right now. Pls shout if you find a solution!
