Each time I try to play a game on Live I get signed out. The game will load, and I'll be able to sign in just fine after that. If I switch games it will sign me out again. This started happening when we switched from ATT to Time Warner. And its ONLY my Account, and not my husbands or my daughters. They can use xbox live absolutely fine. Any suggestions? It doesn't matter if I have auto sign in on or not.
