I haven't responded in a while because it actually started working on its
own. I mounted the NAS again and tried and it worked.
However, this morning, that changed again. The NAS is fully mounted - I can
play songs via the Finder with ease. However, the VOX controller still says
"Loading" in the upper corner. When I try to play a song, the music never actually starts and no Sandbox or any other windows pop up. The thin orange
bar near the top of the controller just keeps scrolling sideways as if it's
loading. When I click the 'next' arrow, same situation. No song actually
plays.
One clue, perhaps, is that I launched VOX prior to mounting the NAS. I
realized that, then quit and re-launched it after the NAS was properly
mounted. No change.
Thoughts?
