I have a course that was originally built in Articulate '09. The course contains Engage interactions as well as a Quizmaker quiz. When I originally opened the course it asked if I wanted to update it to '13 and I did that and saved it. I have made my changes and try to publish and I got the attached error message. The error just says that Presenter '13 has encountered a problem but doesn't state why? Do you think this course will have to be rebuilt in '13?
