css-validator error?

Hi,

I'm trying to run css-validator.war (compiled from source using "ant war"
command). I've placed the file inside webapps directory of Tomcat 6.0.36
server running under Windows 7 (Seven). The first page looks nice - the
same as on the w3c page. When I try validate some pages I've got the
following error (http://s12.postimage.org/dpz9rdl25/css_validator_error.png
):

I've found the following in Tomcat's log files that seems to be related to
the problem:
[error] ResourceManager : unable to find resource
'org/w3c/css/css/xhtml.properties' in any resource loader.
