In reply to Groovnstar:
The credit I used to sign up for Gold membership last year has expired, Xbox Live sent me an email to notify me. And then my box had "ring of death" so I took it to Kwai Fong and got a new one back today. Now, I want to add a credit detail to renew my memberhship but I cannot even sign in (of course!My account is suspended). It tells me to go into "Account Management" but when I click that it says "You are required to sign into Xbox Live to management your account"..........Yes right, how can I sign into xbox live when you say my account is suspended????
