Thanks, but the issue is still there. When I was trying other versions, I'd get a similar issue, so it's more than just this version, by the way (I can't remember which versions did and did not work).
I tried integrating other working versions of Wwise to the Unity file, but they would always fail. The only pairing that worked for me was the most up-to-date version of both programs, but the file I'm trying to work with will only work with Unity 2018.3.14
It just seems the Audiokinetic site altogether is really slow and has a lot of issues. I had to type the initial post in Notepad because the suggested articles popping up froze the site with Javascript errors, and the tutorial section typically takes 2-3 reloads before all images are downloaded properly.
