Hi everyone, I can't sign into my xbox live account. I turn on my xbox and I select my account, and then my avatar does his spin and it says "signing in," but it never signs me in. I've left my xbox 360 on and gone out for an hour & it still says "signing in" on the screen when I come back. It first started a couple days ago and I thought it was maybe a problem with live, but it still won't let me sign in. Does anyone know what is wrong with my account?
