Musesounds got deleted

I had musescore with all the musehub sound fonts working today. I switched audio devices after opening a Musescore tab. The sound was slowed down and lower in pitch (happened for my laptop too). I expect this to happen and I decided to close the tab and open it up again. When it opened all my musehub sounds got deleted as MSBasic replaced it. I checked the download location for the sounds and they are empty. How can Musescore prevent this happening in the future if that?
