Need help to get started

unable to activate Cubase 9.5 program on my computer. requests that I activate hardware, but I do not have an audio interface as I use cables that end with USB and plug directly into computer. do I HAVE TO have this device??? If this is absolute must, then do PreSonus product work or do I have to buy a Steinberg interface?

Thanks, Paul.
tried to post this yesterday but no showing on list. sorry if it pops up twice.

Just activate Cubase don’t worry about the hardware and yes you can you any audio interface.

Go to steinberg’s website and click on the my Steinberg link create an account and activate
Cubase. Once you do that it should go away.
