Sampler Control crash Nuendo8

Right now I am trying Nuendo 8. I am a 6.5 user.
I Can’t use sampler Control in drag and drop. Nuendo 8.1.10 crashes consistently. with the message “Error: A serious problem has occured, please try to save …”
Do other users have this problem before I talk to the support?
Thank you

I’m having the same issue.
