Usually great… but CPU overloads in newest update!??

With the newest update… Mainstage faiing completely. Especially using Native Instruments through it, while using sustain pedal the application will grind to a halt. I consistently get a “CPU Overload” error. Even when using BUILT IN instruments!? I have a late 2013 Macbook pro, 2.6GHz i7 and 16 GB of Ram)…

I is definitely not my machine. If this could be remedied quickly that would be great.
