Today, May 19, 2011, as soon as I signed into XboX Live, i was asked to perform a system update. However, as soon as i started the update, a message showed up that said "Can't download the update. To test your connection,open System Settings and select Network Settings. select Test Xbox Live connection. If problem persists, go to www.xbox.com/support Status Code - 3151 - 0000 - 0080 - 0300 - 8007 - 0570" . This has also happened for Full House Poker( which i spent 800 msp on), Modern Warfare, and Modern warfare 2. Please help me so I can play on Black Ops again!
