No Sound and Stuck Fuel Tank Selector

[lawson-stone]

Recently I have started getting an error message when opening the Sundowner relating to sound. I've attached a screenshot below. IN addition, I am unable to move the fuel tank switch and it remains in the "off" position. I've also uploaded a log.txt file below from starting up through the error message, then quitting.

If you're on Mac you probably aren't running X-Plane under Rosetta. It's required for this product.
