proof of academic status so that you may validate your eligibility

I have a Macbook Air and I was sent an email saying" Please submit your request attaching your proof of academic status so that we may validate your eligibility. Please note that if we do not receive your proof of　eligibility within 14 days, we will cancel your Student and Teacher Edition Creative Cloud subscription."  I clicked on the email and it told me  go to My Orders in your Adobe account, and click Submit Proof. i could not find the submit proof button. my secondary email is my school email which ends in .edu. how do i submit proof?
