I'm trying to install mobile zone on my daughters Apple Mac, and it comes up with an ERROR on installation. "Error running/applications/familyzone/mobilezoneagent/bin/fc-agent-updater_darwin-amd64--service unintall: panic: Encountered unrecoverable error while executing service action: Failed to uninstall Family Zone Filter Client Updater: remove/Library/LaunchDaemons/fz-agent-updater.plist: no such file or directory." No idea what this means. Had the whole thing running nicely for the free trial and now experiencing errors to activate again. Help please!
