Help! Blank screen after restart
Newbie here: I managed to get the latest version of Software Menu on the Apple TV, seemed to be running OK. I used it to install NitoTV and a couple other plugins. Wasn't seeing any NitoTV functions in the menu (was I supposed to?) so I chose 'Restart Finder' from the Software Menu. The ATV restarted and after the initial Apple logo and the intro video the screen is totally blank. I can hear the interface sounds when I click the remote, and I can play music or videos via the iPhone Remote app (album art does display while music is playing) but otherwise there are no menus, nothing.
I can access the diagnostic menu by holding down the Menu and - on the remote. Diagnostics reveal nothing wrong, and it looks like I'll be able to restore it to factory specs (and v2.4 software) if I need to. I'm not sure what I screwed up, hoping all the latest plugins are stable (I did screw up a few times trying to install Software Menu and NitoTV).
Any idea what has happened? Anything I can try before I revert to factory settings and try again??
EDIT: solved it, thanks to help from someone on another board. Was not NitoTV at all, was the ATV Files plugin. Removed it SSH and rebooted, as was well
(exact Terminal command was sudo rm -rf /System/Library/CoreServices/Finder.app/Contents/PlugIns/ATVFiles.frappliance)
