Evaluation try out failed

I’ve been working on a evaluation try out for a month without any problem, until yesterday that I installed the latest update for Mac OS X and suddenly, Rhino stars asking me to validate the license, which is supposed to last until November 21st, any ideas if this has anything to do with the update? is there a way to fix it?
I’m buying the license for windows by the end of the year but in the meantime i want to keep using it on my mac :frowning:

Hi Ivette-

Rhino for Mac - even during the 90 day evaluation - requires that you validate the license. You have 30 days to validate the license before Rhino for Mac will stop saving files (even during the 90 day evaluation period).

I hope that helps,
