Sorry I just see this post today.
about the Demo, it is normal, that is because of the license.
For the crash it is obviously something we must fix.
Could you give me your ticket number if you have one, as this problem has not been reported to me yet.
also give me your platform details (precise OS, DAW versions you are using)
Also just by curiousity, did you try another DAW for the vst2?
