Problems with License on NEW Computer

I installed emclient on a NEW Dell Computer and used the same activation code from the old computer. The old computer is not working so I am only using the emclient on the new Dell. It says under License that the free PRO version ends tomorrow 8/9/2020. What do I do? I only need the emclient on NEW DELL not on any other computer. Why did it not accept my license code from before? HELP.
