Porblems with the validator and XHTML

Hello,

I try to validate http://www.usenet-fr.net/ and i did for the XHTML. See:
http://validator.w3.org/check/referer?uri=http%3A%2F%2Fwww.usenet-fr.net%2F

But when I try to validate the CSS, I get this page:
http://jigsaw.w3.org/css-validator/validator?uri=http://www.usenet-fr.net/

Who tells me to "Validate the XML document first". Where is the problem?
What must I do ? Become conform to XHTML 1.1 ?
