Rhino 7 Evalution ( windows 10) Expired before 90 days

I downloaded the evalution version of Rhino 7 on 20 Sep. and worked great until today and started not to open up. It says that my trial period is finished even though it should be on 19 December. Anu suggestions to solve this problem. Thanks in advance.

Hi Kaleb -

You started your 90-days trial when you downloaded Rhino the first time on June 22nd and that trial period has now passed. If you found Rhino to be of use, you will have to purchase a copy to continue using it. Note, as a student you are eligible for an educational license at greatly reduced price. You can continue using that license when you start working after your studies.
