Update now not working PI

Hi there,

Wondered is somebody could help or had same problem.

I am running xbmc frodo on a raspberry pie.

I pressed reboot to start and all of a sudden when coming back on it started to update itself but now when I start it only goes to the blue screen that says "relax, xbmc will re start shortly."........this does not make me relax .

It restarts and keeps going to this screen,

Anyway know what I've done or what's happened.

Thanks

Antony
