Hi there many thanks for coming back to me, I was very pleased that I managed do what I did as I'm not very good with computers. As for resetting the network I tried to set up a network before when I first got the PC but messed it all up, so I paid someone to come round to do it for me, I will have a read up on how to do it & try it again, if not I will have to get someone in & pay for it to be done "again" (very annoying as was working all OK before the update). Anyway hopefully Microsoft will get it right next time with the updates as it seems that loads of people have had the same problems.
Paul.
