This has happened to me before, I know. I think the problem is Xbox live's. I can't use Xbox.com, I can't log in on any profile, and when I run a connection test it says its Xbox live's problem. It started when I finished a ranked Lone Wolves match; my rank disappeared, and I paniced and logged out. Now I can't get back in. Anyone else getting this?
Also, I'm in England, if it matters at all.
