Does Prologue have big bug issues? VST Performance PEAK!

Hello again!
I’ve been trying out every instrument included in Cubase 6 and I havent been able to try out Prologue for more than two patches. The VST Performance windows says that every time I press a key, my computer goes crazy and it only happens with Prologue.

Are there any problems I should know of?
I searched the forum but I found many german thread that may be about this, but I don’t speak german.
Thank you :slight_smile:
