I have Xbox Live, and everything works perfectly fine. I am able to play games online, join my friends' parties, and stuff like that. However, for some reason, when I try to message someone, it looks like it's gonna work for a second until it says "Messaging
isn't working for your account. Go to ... blah blah blah." I went to the site they recommended and found no help whatsoever. I've already spent a total of about 5 hours on the phone with the Xbox people, and I'm not tempted to go through that again. Please
help me out.
