Error validating CSS

Hello there,

All day today, I've been trying to validate my own and another's website
for CSS, and I've been receiving this error: Servlet has thrown
exception:javax.servlet.ServletException: Timed out.

I saw here<http://lists.w3.org/Archives/Public/www-validator-css/2008Mar/0017.html>that
this has happened before, and I figured I would email before "weeks"
pass again.

If you'd like to test, the website I just tried to test on was was
www.skylinerobotics.org with CSS3, all mediums, and vendor extensions set
to warnings.

Thank you,
John Maguire
