apperantly I cant use my license code for trying the 90 days trial. It said that the license is not more valid even thought In my email from Mcknee siad that the license is valid til 3. of April 2022. Any solutions?
Did you have an evaluation period before?
In that case you are not allowed another period as there is only one free trial per person.
Your free trial was from Jun 1, 2021 - Aug 30, 2021, if you would like to continue to use Rhino please purchase a license.
