Last week, my gamertag was hacked and points were purchased with my Paypal account. I got that all sorted, but Microsoft said that the account was under investigation and I can't connect to Live. When I try it comes up with the following message, even when I'm on Xbox.com:
"There is a problem with your payment option. Please update your payment information to continue your Xbox LIVE membership. You have two options to update your Xbox LIVE membership: edit an existing payment method or add a new one. "
My credit card is valid, so I guess it's just that my account is on lockdown, right? Has anyone else experienced this and if so, how long did you have to wait to get back online?
