EWQL Symphonic Choirs

Hello, I have a question.
I want to use East West Quantum Leap Symphonic Choirs in MS 4 as a VST3.
But the only thing I get is a small screen. (see attachment)
Now I'm using MS 3.6.2: export as midi and importing in Garageband.
That works great by the way.
But I thought it should be easier with MS4 supporting VST.
I hope someone can advise me.
