"Your Product Activation Key Reached Its Activation Limit" problem

I recently bought a new Mac and wanted to move Parallels 10 from the old Mac to the newer. I followed instructions on http://kb.parallels.com/en/122653 but after deleting the Parallels application from the old mac, I'm still asked to buy another license on the new one. I'm a Parallels user from version 5 and this is the first time I encouter this problem.
