Status code: 80004005
Some connection types and Internet service providers (ISPs) cannot access Xbox LIVE Marketplace from the Xbox 360 console. We are aware of this problem and we are working with ISPs to resolve the problem.
Solution 1: Use the Xbox LIVE Marketplace on Xbox.com
You can purchase items from Xbox.com and add them to your console’s download queue. Here’s how:
1.Go to the Xbox Marketplace.
2.In the upper-right corner, click Sign in. Enter the email address and password that you used when you signed up for Xbox LIVE (this is your Windows Live ID).
3.Browse the Games, Add-ons, or Avatar items to find something you want to download.
4.Click Download to Xbox 360.
The next time you turn on your console, the content will start downloading on your console.
Solution 2: Use a different Internet connection
Connect your Xbox 360 console to the Internet at another location using a different ISP. For example, take the console to a friend’s house and connect to the Internet there.
