How can I deactivate my Parallels 11 License when I don't have access to my old Mac

I am trying to activate Parallels 11 on a new MacBook Pro, but I don't have access to my old Mac to deactivate it.
I get a "You have reached the maximum number of activations available for your activation key" error.
Thanks

 

Hi @AndrewL11. We have made some changes to the license key. Please re-attempt the activation now.

 

Thanks

 

You're welcome. Please post again for any further queries.

 

I'm having the same issue with my key. Tried quitting and restarting. Greatly appreciate any help!

Same issue. I don't have my old macbook to deactivate. And when activating on new Macbook, it's not overriding the previous activation. I'm getting message "Unable to confirm the product license - You have reached the maximum number of activations available for your activation key (http://www.parallels.com/eula). Please purchase a new product license."

Please advise how to deal with this issue. Thanks.
