Help me please, yesterday, just before a tournament,the director let me down. It just says 'The active Screen Set (Default) has no screens defined' and is more or less a blank red screen. The settings page does appear but I cannot load another layout as load and save buttons do not work either. Tried to uninstall and reinstall but same happens. I think I have inadvertently deleted the default tournament screen set, but cannot get it back. What can I do?
