When I try to use The Grand 3, Cubase crashes!!

I just installed Absolute 3, with The Grand 3. I’ve seen a few minor glitches on some of the other sounds, but The Grand 3 just flat out won’t work. It crashes Cubase (7.5) every time.

I opened it in stand alone mode and it worked - sounds great!

I can’t find a VST power button. Will this fix the problem, or simply make The Grand 3, and all other VST sounds not work?

I’m using a MacBook Pro with up-to-date OS and 16GB of RAM (should be enough, right?)

I can’t find a solution anywhere. Am I to understand that this simply won’t work?
