Storyline exception

Dear Heros!

 

"Haltepunkt im Quellprogramm wurde ein Haltepunkt erreicht"

"Breakpoint has been reached"

This is the error message when I try to open Storyline. (View the attachted file for more detail)

We tried re-install and activate all Frameworks.

After a re-install, Storyline works perfectly until I click preview this scene or page or after 30minutes it shows the exception. The preview does not show up (only a white screen) and then if I try to open Storyline it shows the errror message again.

Thank you so much!
