Parallels 11 - unable to confirm my license.

I tried moving the Parallels software to a new Mac. Activation key doesn't work. Please reset my account.

 

We have made changes to the activation key. Try to activate again.

 

The Parallels End User License Agreement permits one copy of the software to be activated by a single license key on a single computer.
If you have multiple license keys for the software, you may activate that number of copies of the software on the same corresponding number of computers as you have license keys.
