QUOTE said:Just a word of warning that if you receive an Xbox Kinect game early and perform the title update, it will also update your console to the new dashboard.
Unfortunately, the update isn't the newest version, and every time you try to sign into Live it will try to update to a version that does not exist on the server. Since you can't connect to Live without the newest version, the system will be locked out until the update goes on the servers.
"Due to a retailer error a very small number of customers were shipped copies of a Kinect game ahead of launch," a spokesperson said. "Since Kinect does not launch until November 4th in the United States, customers who insert the game into their console before then will be temporarily unable to access Xbox LIVE.
