"Storyboard ended for the unexpected reason."

I bought the StoryBoard today.
And, when inputting the Serial Number, it displayed “Thank you for purchasing Toon Boom StoryBoard” with indication of “OK”.
Then, I clicked the “OK” button, followed by “StoryBoard ended for the unexpected reason.”

what should I do?
