So something that wasn't immediately clear to me is that if you already own the Music Production Suite 5, they give you a copy of Ozone Advanced 10 and RX 10. I bought it on sale from NI since it was a really good deal, I'm sure others on this forum did too. Fire up their product portal, and it shows Ozone and RX as available to install in trial mode. If you log in to your user portal, it pops up the "Hey upgrade to Ozone 10" loyalty offer. So it initially looks like no, you don't have it, you have to pay for it separate from the pack.
BUT if you go to your purchase history, there they are. In my case Ozone showed up Tuesday and RX showed up today. You then have to feed those serial numbers into the product portal, and they get registered as normal.
Just a heads up to others to make sure you don't throw money at iZotope you don't need to.
