I'm in the same-ish boat. I have an Audiobox 44VSL that I didn't register until today, and I had the Studio Magic Suite available to download. You should have access to at least most of the plugins/instruments. However, I'm not sure if you can only use these plugins in the Presonus-made StudioOne DAW. personally I use Cubase Elements 9.5, so I have given myself access to the Studio Magic Suite, but I'm not sure if there are compatible with my current system. And I'm not sure that I want to switch over to StudioOne.
Hope this helps, let me know what DAW you have and whether or not you were able to make it work!
