How many sets of keys have you ever lost? Take care of the dongle. It’s simply called taking care of business. First things back in the pockets are the fair game & thief bait. The little stuff that annoys you more than losing the big stuff. YOU bought the dongle and (licensed) Cubase. You work in IT? So you know the score.
Soon Cubase will be ON the dongle (but maybe not). Game, set & match. Any computer.
And unless I’m a little confused isn’t there a grace period of 24hrs non-dongled usage on recent releases? Don’t know quite how it works but search around the fairly recent “lost dongle” posts. Someone will know.
