[VU+ Duo] boot loop

[bluey2]

Hi all, I,m a bit of a novice and need some help please.A few days ago I done an online update and everything seemed fine. I recently suffered a very minor power cut which resulted in the box re-booting and losing my network, when i try to restore settings from my usb back up the screen says please wait, background check in progress and then re-boots again. the system information says that i am on build 430, kernel 3.1.1, version 3, last update 20/11/12, thanks in advance.
