No, every offline profile that I have (4) will ALL give the error the first time they are signed in. Does not matter when they are signed in, at the dashboard or in game. Even when the IP6 XBL live account is signed in, they will still give the error when
signed in to XBL.

Here's how the xbox is started, I power it up, use the controller to select any offline account, it gives the error, it doesn't matter if I test or not, when kinect recognizes (or it's signed in with the controller) the next account it will give the error.
When the third is signed in, it also gives the error. Fourth as well.

It does not matter if I test the connection for every test, it will always error as soon as the 2nd or 3rd or 4th account is recognized or signed in with the controller.

well the game is now released and when i sign into with my xbox live gamertag it says account error

When you receive the error code 80151006, it means your Microsoft account IS valid, but is not connected with an Xbox Live account.

Here are some suggestions I found off of the Error Code Database:

Solution 1: Join Xbox LIVE

To sign up for an Xbox LIVE account associated with your Microsoft account, go to Join Xbox LIVE.

Solution 2: Contact Xbox Support

If you already have an Xbox LIVE account and you get this error, contact Xbox Support.
