Cubase Pro 10 asks for activation code on start up

I have Cubase 10 running on a mac Pro OS 10.13.6, I successfully installed with the activation code. I have an old DVD with .cpr files I did on an old version of Cubase and I clicked to open one of the old tracks and I get the activation e licensor window. This must be from the old files from Cubase SX 3 but I need to know what I can do so I can open Cubase 10 from the desktop normally without it asking for the activation code. I would think Cubase 10 is finding old preferences ?


Right click, Open with then select C10

Got it, Thx!
