Activating on a new Mac does not work

Getting crazy trying to activate my Parallels Desktop for Mac on a new Mac i installed with TimeMachine from a backup. Activation Limit reached, you know... But even after deinstalling and restarting it says the same. Followed all instructions but no result. Don't know what to do next...
