I haven't connected to xbox live in months, and when i had tried to, it was telling me that i had to download the latest update. When trying to download the update, it would disconnect me, saying I couldn't download it. So i tried the USB method, and that worked fine. But now, when i try to connect to live, it tells me that the system update is required to sign in, but the update is unavailable. Any suggestions or help anyone can offer? I used a wired connection.
