Why can't I see my Halo 4 stats?

Why can’t I see my Halo 4 stats?

I log into the waypoint website using my Microsoft Account info, I click careers, then halo 4 stats, then it goes to a loading screen that say “retrieving halo 4 stats…”, then a screen quickly flashes displaying error code: 0, and I’m back at the MS account login screen.

Anyone? Bueller, Bueller, Bueller?
