Rhino license key problem

I received my license key today. But my license key is not valid or has been disabled. So i can’t install. What should I do?

It has been disabled because it’s not your first V7 Eval key.
Yours expired on 4 November.
Everyone can have one.

I see you tried a few times using different email addresses, but we blocked that loophole recently.

It seems you have determined Rhino is a useful tool for you to own…

I invite you to purchase a permanent license at:

If you’re a student or faculty, then use the Students and Faculty tab for reduced pricing and proof of EDU status requirements. EDU licenses are permanent, have no maintenance fees, and can be used for commercial work when you leave school. EDU licenses are 80% off compared to a Commercial license.

If you do not buy a license now and need one after you are no longer a student, it will cost $1,000.
