The "Tutorial" commands/queries in the web are all TQL. The above
query is a TQL query.

That's a SPARQL query.

There are different parsers for TQL and SPARQL, so be sure you use the
correct one.

Can you open a GUI terminal on Windowss and execute the TQL query
there? That shell should see that you have a graph with RMI in the
name and connect to the appropriate server for you.
