Audition Global

um... so when trying to make a new account for kau, it told me i had to link it with a previous account i made under the same name/kssn.
it brings me to this page.

i translated everything and i'm aware that it's telling me it will send a code to my email, but when i click the button that supposedly sends it, i never receive an email. would anyone know what could possibly be the cause? i've tried using different web browsers...
