the path to the menuie.css file is wrong:
<!--[if lte IE 6]>
<style type="text/css" media="all">
@import url("CSSMenuWriter/cssmw/menu_ie.css");
</style>
<![endif]-->
should be changed to:
<!--[if lte IE 6]>
<style type="text/css" media="all">
@import url("../CSSMenuWriter/cssmw/menu_ie.css");
</style>
<![endif]-->
