That looks absolutely correct. I see nothing wrong. Are you sure that's the only call to Launch Actor.vi in this VI?
Yes, I think the only call to launch Actor.vi. But I am not sure. I am beginner in ActorFrame.
Ah. There's the problem. You can't just run the Actor Core.vi. It itself must be launced in order for the self enqueuer to be set up. Use the "Init Actor Queues FOR TESTING ONLY.vi" found in the palettes to do direct testing of an actor without launching it (it is labeled FOR TESTING ONLY because it does not work outside of the debug envionment).

Jop.
The problem solved. Problem was in missing launch.vi what launching actor ;-)
