Can't integrate Cufon? What to do?

I have this problem - i can’t get Cufon to work.
I have one static html page, and i want to replace fonts inside h2 tags.

But, it doesn’t work. I searched through their docs, but nothing!
Here’s my code, maybe someone will find something i failed to see

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "">
		<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
		<link rel="stylesheet" type="text/css" href="style.css" />
		<script src="cufon-yui.js" type="text/javascript"></script>
		<script src="Museo_Slab_500_400.font.js" type="text/javascript"></script>
		<script type="text/javascript">
		<div id="header"><div class="clear"></div>
			<div id="header-content">
			<div class="clear"></div></div>
		<div id="main">
			<div class="content">
				<div class="post">
				<h2>Lorem ipsum dolor sit amet</h2>


			</div><!-- kraj content diva -->
			<div class="sidebar"></div><!-- kraj sidebar diva-->

Have you checked that the paths are all correct? Are your Javascript files located in the same directory your HTML file and CSS file is located?

Yes, it’s all in the same directory.
