I cloned the drive on my failing MAC and loaded onto a different mac and need help de-activate current machine so that I can properly activate on the new machine. Keeps telling me that I reached limit on activations. But there is no option to de-activate anywhere. I will buy a new license if necessary - I just need to be able to use Parallels 10 (cant upgrade because I am using yosemite). The instructions online for doing this are not working for me. PLEASE HELP. I tried to buy a license for parallels 17 just to use the activation key for my current parallels 10 problem but that didnt work either.
