EastWest instruments don't play
I have a full orchestra set up in my project, with about 20 EastWest PLAY instruments in it, and it's been going along fine. Now all of a sudden, nothing from EastWest plays. If I create a new project, those instruments seem to play fine (though I didn't save or try much more than briefly testing out to see if they play). If I copy the events in a track from the broken project into the same instrument in the new project, it also plays fine.
In the broken project, disconnecting and re-connecting an instrument provides no change. When I re-connect any instrument, though, I always get the blue box that says "The audio engine has been stopped unexpectedly", and the DROP OUT indicator appears in the Now Time screen.
If I create a new EastWest instrument track in the broken project, it does not play, but I can record to it, and the volume meter moves when I record. But still no sound, either at recording or playback.
If I try to record to one of the existing EastWest tracks, not only does it not sound, the meter does not move, and while it indicates it is receiving Midi info at recording by creating a clip, once I finish recording, that clip disappears.
Any ideas?
