Hi, I cannot help you as I 'm not computer minded it is all beyond me. I just followed the instructions on here & it worked for me. But if you read my posts I'm not happy microsoft for completely screwing up me PC, my PC's are no longer networked like they where before & I cannot afford to pay someone put it right. Also since the microsoft screw up the PC just shuts down all on it's own & then reboots itself for no reason, that is a pain as I have some software running 24/7 for my web site & when the PC shuts down it corrupts all the files, well done microsoft, get your act sorted out.
Paul.
