Thanks for the advice, tried the F5 key to grab everything from cache...still no joy with the last item though. Strangely on THIS page (the 'post reply' form) the ad popped up instantly, (for a gf4) then disappeared and now I am once again waiting for it to load. Maybe the problem is a router somewhere like you said. I am not too worried though, and when I rebuild my system hopefully problems will vanish.
What are you on man?
