Hi What is the query you are attempting to run that is resulting in this "unsupport query type" error ?
Have you been able to confirm basic connectivity of the Sesame HTTP Repository to Virtuoso and its ability to run a simple query and explore the Virtuoso server as detailed in the documentation at [1] ?
