Hi guys, after 12 hours of googling and trying all kinds of different advice I finally managed to work out how to get my WAVES plug ins to be recognised permanently in Cubase elements 9.5
The fix was simply moving the licences from the folder that waves had installed them in automatically to a new folder on the desktop.
I tried all kind of other ways that have apparently worked for others but this was the ONLY fix that has worked permanently for me. Re installing waves central and waves plug ins fresh worked only until i logged off cubase again and then they would be gone on re load.
I hope this helps some of you too as i was pulling my hair out yesterday AND NEARLY GAVE UP.
GOOD LUCK!
