Rhino Evaluation Expired before 90 days

(Rhino 6 Evaluation 90 Day Trial Problem)

I just downloaded and installed the 90 day evaluation Rhino 6 for Windows version onto my computer. It asked me to enter my email, which I did, and then I got a email asking me to confirm my email, which I did. Then I created an account online but when I try to open up Rhino on my computer, I message window pops up with the title “Rhinoceros 6 Nees a License” and below it it says Login as “my name” or “log out”, “enter your license key”, “use the zoo”, or “buy a license key”.

I have no idea how to get it to run. Can someone help me and walk me through the steps? my email addres shyamlidas3@gmail.com
