Export not working

Hi there I have the toon boom harmony essentials trial and when I go to export everything seems fine but when I go to open it it never actually saved/exported. I have no idea what I am doing wrong can someone help? Thank you!

Be sure to have Quicktime Installed and up to date. I had the exact problem, and it works fine now for me.

I have quicktime installed but its not saving or exporting in fact when I click video or sound options nothing happens, no other dialog boxes open, nothing.
