Hey guys, completely new to the forums, first ever thread.
I won a copy of Halo 2 today (PC, brand new, unopened and seal intact 
All installed fine - yay!
Then, a wild error appeared - 8007065b
I’m halfway through downloading my Xbox live profile and then it stops with the aforementioned error code being displayed and “can’t connect to Xbox live” accompanying it. Xbox support suggests changing/altering ports but every website/ forum I go to gives no help on the matter - i.e what the hell a port actually is 
(Needless to say - I am a noob in such matters.)
I would much appreciated some light on this issue if anyone has the time - thanks
(P.s: I have no idea if it has any relation but I can login to “Games for Windows Marketplace” just fine. I’ve also restarted my PC and none of my antivirus services - to my knowledge - prevents communications between xbox live and my computer etc.)
