Could not access http://www.gr00ps.com/en/opensearch/node: response code 412

When I go to http://opensearch.a9.com/newColumn.jsp to submit my description file I get the error, "Could not access http://www.gr00ps.com/en/opensearch/node: response code 412" from A9.com.

Same thing for the other description file at http://www.gr00ps.com/en/opensearch/user.

Searched around and I couldn't even find what an error 412 is. Any help would be greatly appreciated, thanks in advance.
