Sorry to hear you are having problems James. You mentioned Ozone Imager. I am assuming it's Izotope's Ozone Imager?
Anyway, I thought I would mention that they give that plugin away for free now, you can use an installer directly from them to install it and activate and use it rather than using waves, that's what I did although I haven't worked with it much yet, so I don't know if it has the same problem with the presets saving and such things.
Here's the link to the information and download page from Izotope.
https://www.izotope.com/en/products/master-and-deliver/ozone/ozone-imager.html I'm thinking it's the same plugin, so perhaps if it is then you can install it this way and bypass the issue with Waves.
I have a couple of plugins from Waves that were giveaways, the One Knob Louder and VU Meter, but that's the only reason I have waves on my PC right now, but I do plan on buying a few plugins from them in the future also, they have had a 29 dollar sale on several plugins I got an email from, so who knows, I may purchase some soon.
Anyway, I hope this helps you out, you've always had some really good input and advice on things for others, including me that I have read here from time to time. Good luck!
Happy Holidays!
