XBMC icon not showing on ATV 2

Got a friend who is trying to install xbmc on his ATV 2.
He got NITO tv installed and the icon shows
Then he went into NITO TV installed xbmc and then restarted and his XBMC does not show up on the ATV

Then he went and did the xbmc install via the wiki and installed but it said XBMC was allready installed.
rebooted again still no XBMC icon. And i am not sure of what would cause this issue.

thanks

He is running 5.1.1 on the apple tv 2.
