Hey! I have a question concerning the Club GreenSock License. I hope this is the right place to ask! ? I have been using the free version of GreenSock for quite a while now and I am now planing to get a hold of the SimplyGreen Plan in order to get access to some of the bonus plugins. Before I dive into new projects I wanted to ask what happens if I decided to stop renewing my license. I understand that I won't be receiving new updates for the plugins. What i was wondering is whether I am still allowed to keep the old version of the plugins in my projects even after the license ran out. Or does this mean I have to either keep paying for the license or remove the script out of my project. Thank you in advance!
