I get this error when trying to activate on my new mac. This license is already in use. How would you like to activate Parallels Desktop on this Mac? You can either use the license with Parallels Desktop on this Mac, automatically deactivating the license on the other Mac. Or you can purchase a new license. //after trying to activate You have reached the maximum number of activations available for your activation key (http://www.parallels.com/eula). Please purchase a new product license. My old mac is dead and can no longer log out. What can i do?
