For some reason I cannot connect to Xbox Live. It was working perfectly well, but when I went to sign back in after an hour break the following message appeared: 'A SYSTEM UPDATE IS REQUIRED TO SIGN IN TO XBOX LIVE, BUT THE UPDATE IS CURRENTLY UNAVAILABLE. IF THE PROBLEM PERSISTS, VISIT WWW.XBOX.COM/SUPPORT' I am using a wired connection and when I test the network connection it connects all the way through to the Internet but fails at Xbox Live and then reports the above message.
This has now persisted for 24 hours and I am now looking for answers from your team. I have cleared down the cache but other than that I am mystified. It went from working to not working within an hour!
I look forward to your reply.
