Problems with eLicenser

Hi there, i’m on my Mac Pro running Yosemite. It annoys for some time now that i have to have my eLicenser Control Center open in order for the licenses to be validatet. If i don’t do so i get an error fx on ReFX Nexus that no license was found. Why is that? But when i have my control center open it works fine. Can anyone help me figure out what is happening?…?
