Yes, a total insurance policy.
Even if you don’t make a living with Cubase, there is usually a trial version available. In cases where the dongle has to be replaced you can get an auth code for the trial version without waiting, and get back to work. So you could just have a second blank dongle stashed away.
And also, upon buying Cubase new, You can buy a second dongle and place the license on that. Put the included one in a drawer. Dongles sold with with new boxes (read not update or upgrade) come with a license that will run any Steinberg software for 25 hours.
There are several ways to avoid this grief.
