Cannot activate Parallels after moving to a new Mac

Hi,
Could you help me please. I had Parallels installed on my old Mac laptop and I have to move it to a new one. I have uninstalled Parallels from the old Mac, rebooted it and installed it on the new Mac. When I try to activate Parallels on the new Mac with the license number which I have I'm getting an error saying "Please verify that you entered the license let correctly, contact your administrator".
What should I do to activate it?
Thanks

 

Hello,
Could you share your license key via the private message please?

 

Hi Maria, could you please send me a private message first so I can reply to it? I cannot find the option for private message anywhere
