Check Windows Event Log for errors (Control Panel, Administrative Tools, Event Viewer). Patriot logs to the Application log. Both services and the client will log there for errors.
Note that it requires adminstrative privilages to setup the source in the event log. If you aren't getting any entries in the event log, try logging into the machine as an adminstrator, and starting up the Patriot client (run as administrator). This should setup the source in the event log and allow other users to then write to it.
