Changing xunlai house Email

When i registered my email for the Xunlai Tournament House i typed it wrong. Now, i don't know how to change it as on the webpage i only can find the "resend confirmation email" and "forgot your pasword" options... so, as the email i wrote isn't mine, that options are useless :/

any ideas?

ty in advance
