I just sent in my xbox for repair, and got it back the other day. I plugged it in, and when i logged into xbox live it said ” can’t sign into messenger.” Then, when I started playing the connection was horrendous. My connection has always been fine, and when I hit check connection, it is perfect. The game play is fine offline, and when i tried signing into messenger it said the password is incorrect, which it’s not. I called in xbox support and they were no help at all, does anyone know what is wrong?
