I've updated the settings. Installed all the ATV Flash updates necessary. I've installed Dharma, still doesn't work. I've installed Eden, still doesn't work. The other option is "Rev. 20120430", which is some kind of update? But that does nothing as well.
I've started from scratch--I put my ATV silver back to the factory settings. Updated, reinstalled ATV Flash, updated from there. I though that might solve the problem but no, XBMC simply will not load. I always get "Error: Cannot launch XMBC/Boxee from path: /Applications/Boxee.app/Contents/MacOS/XBMC". At my wit's end, don't know how to proceed.
