*** Remove init script and other files ( '''/etc/init.d/sabnzbd''', '''/usr/bin/sabnzbd''', '''/var/spool/sabnzbd''')
*** Remove '''amahi-sabnzbd''' RPM (in case this was not removed on uninstall)
*** You will find a backup of your settings from the uninstall at '''/tmp/sabnzbd.ini.bak'''(in case you forgot to copy it).
If all goes well, you should now have the latest version.
