What's happened to my ATV2?

I’ve set up my Apple TV 2 with aTV Flash (Black) and it has been working great…until yesterday.

Now Netflix has disappeared completely from the menu and playing music from my iCloud no longer works.

Regarding the latter problem, I can see all my iCloud music and navigate all through the menus with album artwork all showing but if I select a track to play it I just see the rotating loading circle no matter how long I wait. I can stream music from the iCloud on my other iDevices both on my home network and using 3G.

Can anyone suggest a solution please?

Sorry, all fixed now. I’ve just read the FAQ about Overflow and that followed by a reboot fixed it.
