Greetings MMO-Champion!
Just dropping by with the reminder that if you ever need our assistance but can't log into your account, you can select the live chat or phone callback options from the bottom of the following page. The secret question to the account is requested, however if that's not available you can put 'I don't know' and proceed with the listed steps.

Live chat and phone callbacks have different hours throughout the various regions, to check their availability in your own region just hover over the appropriate selection there when you see it at the bottom. Additionally, tickets can be submitted 24 hours of the day. Hope this info helps! Let me know if you have any general questions about that.
