I have been trying to download the new Update off and on for nearly two months now.
My dashboard has changed to the new configuration, however: a) My avatar remains blank, and I cannot access the avatar options; b) I cannot play any downloaded avatar-based games (Kingdom of Keflings, Doritos Crash Course, etc); c) I cannot access Zune at all to play downloaded game videos (even offline); d) even when my connection screen informs me that I am connected to the internet, it will not connect me to Xbox LIVE (which means I also cannot gain access to Uplay)!

Update Error Message: "Can't download the update. To test your connection, open System Settings, and select Network Settings, Test Xbox LIVE Connection".
Update Error Code (6 sets of 4 digits/letters each): 3F45-0000-0080-0300-8007-2EE2 ( -2EE2 comes up the most, but have also had error number group endings of -2746 and -2751 for some reason)!
What you've tried: All solutions tried again and again, mostly with exasperation and/or blind and idiot optimism. I cannot even download the update onto a USB, as I end up getting a Network System Error when I try to download it. Plenty of space left on Hard Drive, System Cache dumped so many times it is not funny, simplifying network does nothing, Firewall up and down - ditto, and inserted and reinserted storage device so often I think I am getting Carpal Tunnel. Nothing works! I can still play my Xbox 360 game discs and DVD discs on the console, but that is all.
My computer is currently running Windows XP (but I have updated Internet Explorer to IE8) and has never given me any problems when it came to downloading earlier Xbox updates. I can use the internet on the computer normally, so it doesn't seem like a problem with the Optus Network.
So, why is this update giving me so much trouble?!
