When trying to upgrade my account to the PRO version i wanted to get a student discount because i am a college student. I accidentally made a minor typo in my student email address and i cannot find a way to change the email that they send the promo code to. When i click on the link that referred me to claiming the student discount, it just keeps saying an email has already been sent and does not provide me with a method to change the email. Is there anything i can do to get the student discount?
