Deactivate license to use it on new computer

I have uninstalled Toolbox on my old Macbook and installed it on my new Macbook. It still shows my license is active so I can't use the tools on the new machine. Do I need a new key, or the activation count reset?

 

Hello, kindly help us with the screenshot of the error message you are getting.

 

I'm not sure what changed but it is working today. Thank you for following up.
