This happened to me about a month ago and i still cannot go on to xbox live. I was playing on xbox live gold perfectly and now it says I am not a gold member anymore. I did get a new credit card number and updated everything to adjust to that and I end up getting "Sorry, that's as many as you can have. Only a limited number of these are allowed on any one account". So I cant play xbox live because its not registering me as having a gold membership and I'm unable to purchase a new one. Any advice on how to fix this would be greatly appreciated.
