Send crash dumps to support please.Yeah, happens to me too. In VEPro though. Just crashes for no reason. Not often though. Yesterday it crashed when I hit the "mood" button to change it to Epic. I took it as a harbinger. Stay away from Epic music.
In all seriousness though. Opus is way more stable than Play when it was first released then Play became one of my most stable plugins. I'm sure given enough feedback from us public beta testers they'll make Opus just as stable as Kontakt. It's a great little Player and I wish them all the best with it because I know that soon I'll be depending on it. It sounds so good.
