Hi there, I am trying to reactivate Parallels 10 on a Macmini with macOS 10.15.7 Catalina. I got following message: "Your product activation key has reached its activation limit and cannot be used to activate Parallels Desktop. Please use a valid key or contact the Parallels Support team for assistance." I have a valid license-key but I have no access to the old computer to deactivate the license, whether in my Parallels Account I can`t deactivate any computers. Thank you very much for your help! Best regards, MatthiasD8
