Unable to confirm product license :(

I just replaced my computer after the old one was stolen. When I restored the new one with Time Machine, my Parallels gives me this message that I've reached the maximum number of activations! What do I do?

 

Hello beta_bluerazr, please quit Parallels Desktop now. Then, open Terminal (Finder > Go > Utilities > Terminal). Inside the Terminal window, enter the command 'prlsrvctl activate-license-online' (without the quotes) and hit 'Return'. Wait till the operation completes. Then, close Terminal and re-attempt the activation.Thanks!
