IE 7 doesn't read my CSS code

[egadfly]

I have a site that has worked fine.
Suddenly users email me saying that with IE7 nav columns are not appearing.

Anyone have advice or a place to look?

Do you have anything in your code that looks like this?

<!--[if lte IE 6]>
<link href="http://www.devlib.org:443/templates/rt_vortex/css/template_ie6.css" rel="stylesheet" type="text/css" />
<![endif]-->
That would case the stylesheet to not load when someone comes in with IE7.
