What version of the Adobe software are you running?
most recent 12.1.2 (I auto update)
Win or Mac?
Mac. (sorry, thought my auto-signature was on when I posted)
Any changes/installs on the system at the time “queue” stopped working?
nope
Is “queue” gray-out/unavailable, or does clicking it simply do nothing?
no. I can export using media encoder… but the captions aren’t there
If you manually launch Media Encoder first, does “queue” work then?
queue works… just no captions
