Lost AI Traffic Sounds

[CFIJose 5,485]

I noticed yesterday that my Traffic360 AI traffic engine sounds were gone. I wonder what I installed that caused the sound to vanish?

If I reinstall client, would this bring back AI engine sounds?

I have been considering  AIG AI, but old habits die hard. If I go that rout, will I have realistic engine sounds at the airports and not in the air? Aside from the poor AI textures, loud AI engine sounds while airborne was my only criticism of Traffic360 models.

In a way I'm  kind of happy that they are gone, but I'd like to know.
