Windows 10

Finale Version 25

ARIA Player 1.872

(AISO 4 ALL v2 is responding with ARIA Player, I am not sure if that is a problem)

Aria Player will not produce any sound in standalone or within finale. I load any instrument, and my MIDI controller input is received, but no instrument will produce any sound.

I have attempted reinstalling and restarting.

What might be causing this?
