spring-security-3.0.4 missing?

Hi

My application has recently stopped working, reporting the following when attempting to start:

org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema document 'http://www.springframework.org/schema/security/spring-security-3.0.4.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.

When I go to the directory http://www.springframework.org/schema/security/, I notice that spring-security-3.0.4.xsd is missing.

Would I be right that this missing file is the cause of my problems? If so, can it be reinstated?

Regards

Jason

As an FYI this should have been resolved earlier this morning.
