MainStage Error Audio Unit Problem

"An Audio Unit plug-in reported problem which might cause the system to become unstable.Please quit and restart"

Also a button called recover, which if clicked, brings up the dialog again usually 2-3 times with clicking recover, the concert finishes loading and works properly.

Plug-In Manager says everything is good.Every so often the concert loads with no problems./

(?)

Thanks to anyone who might have insight to this!
