Hi, i just have bought a update version from parallels desktop 13 to 14 as suggested in my software but when i will put the key i have received the message "you have entered an upgraded key. Please confirm it with the key from the previous version" request my previous key that I put and receive always the message "The product key of a previous version of Parallels Desktop has been not accepted on the license server". How can I validate it? or please get refund to me.
