It looks like it was designed by Jon Baker (jdavidbaker) from the vNFL. It probably uses Greg Stelmack's DBupdater
to update the database after every sim. You'll need access to your MySQL database including the My SQL server, port number, database name, database username and password in order to update the database. As it sounds like it isn't hosted on your machine, unless it is hosted on someone else's machine who can get you that information, you'll need to get that information from the previous commissioner - or whomever was running DBupdater after every sim.
Finally, Jon is a member here and you could drop him a note
and ask him if he has that information as that does look like his work.
Hope that helps.
