NIS 360 Premier not working URGENT

I have NIS 360 Prem 3 user which has stopped working on one of my laptops. Works on other one!

It says I have trial version while my other laptop is working properly. Could I have been hacked? How can I reinstate my working NIS  360 Prem which was working a half an hour ago? I have tried download which says I already have NIS360 Prem? but when trying to run it it reverts back to claiming I have trial version???
