When Windows 8 is configured to connect to a home group, it won't want to connect to your WiFi router.  This prevents TournamentSR from presenting brackets and team scores when "File", "Start web server" is selected.  This is the case if the "Web server" address is shown as "http://127.0.0.1".

To fix this issue, go into the control panel and navigate to the network settings page.  You must disconnect from the home group and the computer should stay connected to your router.  The next time you use "File", "Start web server", the address shown will be something other than "127.0.0.1"
