I've reported the website problems. You don't need your order number. When it starts working again simply go to your account page: http://home.mcafee.com/root/MyAccount.aspx and download the software.
If any difficulties with licenses not being available phone Customer Service - it's a free call and linked under Useful Links at the top of this page. (When it starts working ;-) )
I think the other connection issue is probably related to the site being down.
The website is restored.
