I keep getting evaluation license keys that are expired

i keep getting evaluation license keys that are expired. I have installed Rhino 7 and they ask for my email, no problem. Then they ask for my license key, i copy paste it from the email and it says that it has expired in the program while on the mail it says it will expire by march 2022. I’ve tried with another email and have gotten the same result. I don’t know how to fix this.
Thanks in advance

Our 90-day evaluation is limited to one per person. Trying to circumvent that limitation is not allowed.

You have had already several evaluation periods.

The fix is easy: if you want to continue using Rhino I invite you to visit Rhino - Buy - Rhinoceros and acquire a full license. Note that as a student you could be eligible for a big discount - educational licenses can be used commercially, even after you graduate. The buy page has more information.
