First, you need to check if the licence is valid at cpanel:

then, run the following command:
At this point, your license is up and running!
Just a remark if you already had an active license from another supplier you must first guarantee that is already expired when getting the new one if don’t do this you may have the license blocked in the meantime .
If this happens you just have to open a support ticket on your supplier to get this sorted.
