Yeah, this has happened to several people over the last couple of days all over the place. It is not a "Rage" issue per se but rather an "xbox live" issue. It has been happening w/ me for several days now, usually reflecting a gamerscore off by 50 points
or so and always showing an older gamer pic. I have tried "recovering my gamertag" a couple of times and I am also on "live" when I play. There are mentions on various forums about this, including xbox support so hopefullt they will have it trimmed out soon.
