If you can't get this to work on your Mac, you're not ready for it (or maybe you just don't deserve it. Whatever. That's between you and whoever runs your life for you).
But more than likely you're just not ready to put in the time to do the things you need to do to run the software without problems. It's a pain in the ass but the only way to guarantee an app wont die on you in the middle of a production session with that hot singer you finally got to come over your crib to record vocals.
You need to install Little Snitch which blocks apps on your Mac from calling home - most of these apps contain a script that contact the developer's web site behind the scenes to make sure you have a valid license, if you don't, the app will stop working.
You need to find & install CodeSigner and DeQuarantine to get process new apps to get past Mac's GateKeeper. That applies to most apps released after 2020.
You need Parallels Desktop so you can run Windows on your Mac in what's called a "Virtual Machine". Most of these apps use a KeyGen *(.exe) that will only run on Windows.
And you need to isolate the new app you downloaded from here from other apps you have installed by the same developer. Or it will stop working.
