The free trial is over, now I want to use Rhino to practice, so without saving.
But the program keeps asking mee for my license

In order to use Rhino as a viewer, you need to move your expired license out of the Cloud Zoo and lock it to the computer.
See the bottom note on this help file for more information: Frequently Asked Questions: Licensing in Rhino 6, Rhino 7 and Rhino 8 [McNeel Wiki]
