My License Key is Invalid

I just downloaded the evaluation version of rhino, and after I enter my license key, it said the key is not valid or has been disabled. How can I solve this?

I see you used a V7 evaluation license already and it is about to expire.
You only get one.
You’ll need to purchase a permanent license now.

If you qualify for an EDU license, the price is much lower than a commercial license.

i’ve just created an account and when i enter my email it says my account couldn’t be found. When i try to enter the license key that has been sent to me, It says it has expired but the email says it expires May 2022. Any idea why?

You’ve already had a license Sep 13, 2021 - Dec 12, 2021

One per person, thanks.
