Parallels desktop 10: "You have reached the maximum number of activations available"

I'm trying to activate Parallels 10 on my new MacBook Pro. I already removed it from my previous mac, but I keep getting the maximum number of activations error. Can you help me? I tried to "deactivate" the license in the old mac, but apparently Parallels Desktop 10 doesn't have such option.
Thanks in advance!

 

We have made necessary changes, try to activate again.

 

I have just tried again and it still doesn't work. My Parallels Desktop is in Portuguese, but here is the translated error message I get: "You have reached the maximum number of activations available for your activation key....."

 

Here is a screenshot (excluding the license key, naturally).
Thanks in advance for the assistance!

 

Please follow the instructions below:
1. Quit Parallels Desktop, then try to activate after launching it again.
2. If you are still unable to activate, Open Terminal on the Mac and execute this command: prlsrvctl activate-license-online

 

It worked after executing the command "prlsrvctl activate-license-online".
Thank you very much!

 

Glad to hear that! Feel free to reach us anytime for support.
