Need help with website link

First my layout looks different in IE then in firefox. When i try to validate the site its saying Found 2 errors in external css files [Microsoft Internet Explorer 5.5, Microsoft Internet Explorer 6.0]
<link href="file:///C|/Documents and Settings/Lavincent hooker/My Documents/Green/subordinate/subordinate/default.css" its saying this link is linked to my documents, but there isnt anything like this in my documents. at least i dont think so

 

what are you talkin about? explain...why do u have something linked to your desktop

 

you use please conditional CSS like

<!--[if lte IE 6 ]>
<link href="css/ie6.css" rel="stylesheet" type="text/css" />
<![endif]-->
