A Big Jump From P4 !! ----------------------------------- I'm sorry, I have no idea how the Mac version is licensed. Have you re-installed several time ? Switched to better hardware without un-installing program from old kit ? Transferred to an SSD ?? May I suggest contacting Smith Micro directly, as they would have records of the installs ? If the hardware those ran on is now trash, they should be able to help. One way for them to be sure, to be sure is to send you a new license number. You'd have to un-install every instance of old, blocked license, then register with the new one. Make sure your libraries are safe before then !!
