Hi there. Rang the helpline and was talked through the stages, that I may add I've tried many, many times, and when we reached the stage when the person on the other end confidently said "right-now you should have restore in front of you" and I said that it was greyed out I got a surprised "oh-I'll talk to an engineer and get back to you" Anyway, seems we have a fault, no surprises there. We are covered by a "whatever happens" warranty and they will be out to see to the problem on Wednesday. So glad it's not me, I was beginning to feel stupid.
