Nothing is wrong with the code on the template... The issue is with the code on the pages.
Normally if a page is derived from a template, DW will automatically update the paths from the template....
However we use IE conditional css, which looks like:
<!--[if lte IE 6]>
<style type="text/css" media="all">
@import url("../CSSMenuWriter/cssmw/menu_ie.css");
</style>
<![endif]-->
The fact that this code is in a comment prevents DW from updating the path properly, so you have to go to the individual pages and update the paths manually before it will work. Do you have a url of a page demonstrating the problem? I could tell you what to correct on that page, the template itself looks correct.
