Hello Everyone,
I’m sorry for this situation and the frustration you have around it. It’s really really difficult for us to find the reason why you have this issue and we need to make more investigation about it.
That being said for those who have the issue, you can find the older version fo Audirvana 3.5 below but make sure it look at the procedure below if you do not want to loose any of your Favorites/playlist from Audirvana:
Before installing this older version, make sure you have made a back up of your AudirvanaPlusDatabaseV2.sqlite file.
You should find it here:
C:\Users[your login]\AppData\Local\Packages\Audirvana.Audirvana-[… id number that can vary]\LocalCache\Local\Audirvana\AudirvanaPlus
After you have made the back up, uninstall your version in the Windows 10 settings in the App section.
