We have made necessary changes, try to activate it now.I just upgraded to a new 2016 MBP and I'm getting this error.
After installing Parallels 11 on my new MBP and signing out of Parallels on my old MBP, I enter the Activation Key and get the "This license already in use..." message. When I click "Activate on this Mac", I get a message that says "Unable to confirm the product license. You have reached the maximum number of activations...".
Why would I still be getting this error if I'm signed out on both of my Macs? Would someone please help me get me license reset?
