N.I.S 2009.Cannot access live update server !

Further to my probs last week connecting to the internet, after I thought we had fixed it, ten mins later, i lost all internet access and e-mails. The problem was that I could write the I.P. address in the address bar and it would then connect, but not words !!! After spending nearly £50 on calls to premium help lines i.e Virgin and P.C world they came to the solution that I would have to do a full factory reset. This i did and here I am    all back to normal. Just make sure you back up all your data or you will lose it. Thanks to the guys that helped me last week. Alan
