Karamba3dGetLicense not working

Hello there. I installed Karamba3D with the Package Manager on my Mac. Later then I bought an EDU license from the Karamba3D website. Now I want to activate this license. But if type the command Karamba3dGetlicense nothing happens. There is also no preview for this command. It says unknown command.

Do you guys know what to do?

the mac does not support the cloud license, and currently a temporary license is offered.
