Yes I started it as admin(As in DBoy's guide) and as of my last notice, I don't have a Firewall enable(Windows Disabled)... I uninstalled my firewall / av in case that was the problem(which it wasn't)... and in case I added an exception to a disable windows firewall, which didn't help either..
My brothers computer( who is on same network ) is having no trouble at all connecting, though he is running XP
