This morning, I'm frequently (every minute or so) told that someone else has signed onto my XBL account (no one else has the info) and when I immediately sign back in I'm told that it was last signed in on another console. When I try to go to xbox live's site to change my password, I'm unable to access any xbox live sites on either firefox or IE (all other sites are fine). Has anyone else seen this? Do you know how to fix it? Is someone hacking my account? Is XBL in general being hacked (which is why I can't get to their site)?
