Elements keeps saying it is unlicenced.

I purchased Elements 15 for my new computer to go along with CC Photoshop I have on the cloud. The program keeps running for a few days and than stops and says it is unlicensed go to the Editor and update the license. I can find no way to update the license and when I go to the web site it says I have no program registered.  In the editor certain functions are turned off as well. When I reload the program it again runs for a few days like maybe its a trial version than stops and says to update the license. I have entered the code

I have used Photoshop for like the past 15 years so I am no new to it. What am I missing. It's been two months now and I have gotten nowhere.

Any help would be much appreciated.

Thank You
