My account expired today and was trying to access my account. For some reason http://us.battle.net refuses to load up for me to even get in. Anyone ever had this problem or is the site down? I can view the message board and armory at all either.
You are most likely using Google Chrome. This bug only happens for Google Chrome users as far as I am aware.
Try power cycling your modem/router, opening up Internet Explorer, and retry. After successfully loading the site on IE, switch back to Chrome, and see if it works.
