Thanks for response, reboot and restart.First rented game, sign-in failed. Returned that, purchased new game. Still sign in failed. Original post here, then response to "reboot and restart". Real novices here. We deleted BIA entirely from X-box. shut off amchine power. Back on. insert BIA. Create profile. Sign-in failed. Repeat threee times. Please advise. Thank you very much in advance.

I'm getting the same results. I suspect the XBox needs to be connected to the network. If so this is a bug for a non-networked XBox.
