The project or one of it's work units has been saved with a more recent version of Wwise, and can't be opened

Question

I accidentally opened one of my projects in a newer version of Wwise, than Unity is capable of reading. Even worse, I instinctively hit save on the way to close it out.

 

Now I can't get Wwise and Unity to play fair. New version of Wwise opens the project fine, but the sound banks will not load, and I can not open the Wwise project in 2019.2.5.7349 which is what is required for everything to work right again.

Is there anything I can do to get this working again??

Hey Brendan, 

Sorry to hear this happened to you. Could you check to see if you've got a .backup folder in your project? 

If not, I believe you might be able to recover a few things by simply copying and pasting code from Work Unit to Work Unit. 
Take a look at this video - https://www.youtube.com/watch?v=4BjcDwav-Ww
It won't show you how to recover it, but it shows how you can take code from one work unit and paste it into another. Once that's done, replace the Originals folder to get the audio files associated with the containers. 

That said, it's always a good idea to use some kind of versioning system in case this happens in the future, like GitHub. 

Hope you get some of it recovered.
