Toon boom studio 4 crashes when exporting

Toon boom is annoying me at the moment because I cannot view my animations due to toon boom crashing everytime I try to export the movie.
Any suggestions on how to fix the problem ???

You can try to uncheck the Preview Movie after export option in the export dialog. It might be causing the problem.

I’m new to this so how do I do that?

The check box should be at the bottom left of the window where you enter the export settings.
