Unable to confirm product licence

I am trying to switch my parallels licence desktop 11 from my old mac to a new one. I have deactivated the licence on the old mac, signed out etc etc. I'm still getting the message unable to confirm the product licence when I click to activate on this mac.

 

Hello, we've made some changes with your Parallels Desktop 11 license key. Please check the issue and let us know the results.

 

Thank you, fixed now

 

Thank you very much for the help buddy, I got to know that there is an update.
