I've been online since September 2004.
In 2007 Microsoft errantly cancelled my subscription for 4 months. My anniversary became January 15th and instead of going from 7 to 8 years last week, it went to 5.
I've attempted to follow the guidelines given here: http://forums.xbox.com/xbox_forums/xbox_support/f/12/p/439018/2197296.aspx
Profile re-download and system cache clearing, but nothing has fixed it. Does anyone have a solution?
