I'm currently following this one up with EA, but is anyone else receiving an error message about Xbox Live Membership Limitations when trying to access their inbox in the Player Hub or send out invitations for leagues/Brotherhoods? Normally this would point to a subscription issue, but my Gold Membership is definitely valid, making it quite a puzzling issue.
Anyway, if anyone else is experiencing a similar problem please let me know; the more info we can give EA about issues like this, the better.
