My friend just tried logging in (has had no issues since he started) and he is being presented with "Sorry This User Does Not Exist" error now. This is his profile on the forums: http://forum.naruto.oasgames.com/en/home.php?mod=space&uid=112819&do=profile
Can a customer service team rep help him retrieve his account back or figure out what is going on and why he can't log in anymore?
