I have just recently bought a wireless cable for my Xbox I tried to access my Xbox live account but it won't let me. Every time I try to put my Windows live ID and password I keep getting a message saying "The Windows live ID or Password isn't valid." I tried changing my password to see if that would help but it didin't help. I can access my xbox account on my computor but I can't access it on my xbox 360 for some reason. Can any of you help solve my problem?
