disabling autostart on mac not server will not start at all?

Serviio automatically starts on OSX after the system boots. To disable this behaviour, follow these steps:
1 open the daemon configuration in your favorite editor: /Library/LaunchDaemons/org.serviio.server.plist

2 disable autostart by changing <key>RunAtLoad</key>
3 <true/>
to 
<key>RunAtLoad</key>
4 <false/>

5 and save the file

now how do i start serviio app the console just says that the server is not running?

i tried

sudo chown root /Library/LaunchDaemons/org.serviio.server.plist

start the server sudo launchctl load /Library/LaunchDaemons/org.serviio.server.plist

stop the server sudo launchctl unload /Library/LaunchDaemons/org.serviio.server.plist

nothing works?!?!

help

I would like also disable autostart!
