Trial expired earlier

Hi there,

Not sure if its the right place to post. I have installed trial to out Rhino and I now I have a problem with validation key as it expired earlier than it should have had.

What do I do?

It looks like you figured out you needed to Validate your license.
The license needs to be Validated within 30 days or it will stop saving.

Is there some reason you did not validate the license within the first 30 days? Did you not run Rhino? Did you never Quit the Rhino application and restart?
Rhino should have pestered your about it and warned you.
