Since the education/non-profit discounted rates are non-recurring, you will have to renew your subscription at the following page, while logged into the account for which you wish to renew the upgrade:
If you don't have a .edu or .org email address, you'll need to click 'here' where it says at the bottom "I don't have an education/non-profit email address." You'll then be prompted to send us an attachment as proof of current affiliation with an education institution or non-profit.
Please let us know if you run into any issues in the application process!
We love our students, teachers, educators, non-profits and charities, and want you to take advantage of discount Pro pricing year after year.
