Please check your SPAM folder first. If it's not there, check if the e-mail address you specified in the Registration form is correct: fill the form again and click Next. If it lets you continue, that will mean that the e-mail address was misspelled previously, and you'll have to register again to receive the code. But if there's the "e-mail is already taken" error, it will mean that you have registered with the correct one, but our confirmation code got blocked by your e-mail server. In the latter case please contact our Support team at firstname.lastname@example.org for them to confirm your account manually.
