How can I change my username or password?
you can just change your password by going to the following URL: https: / / topup1.levelupgames.com.br/login.aspx? ReturnUrl =% 2fMyAccount.aspx and access your account, then click on Perfect world and change password
There's no option to change their names for users. If you want to change your username, you need to actually create a new username with another email address, then you will be able to connect to the server.
