Please help, uninstalled NIS09 with 39 days left on trail. now have only 15 days left...

Anyone that could help please qadvise… I got NIS09 when I got my computer on 2/13… It came with a 60 day trail…  I have until April 15 before it expires… anyways, I tried to unstall updates and it removed that trial with the 30+ days left and re-installed a program with only 15 days of trial… How do I get the program back that expires on 4/15. They’re both NIS09 version 16.2.0.7
