Republishing course with new versions of videos

Hi Thomas! Thank you for sharing detailed information on what you are experiencing when trying to change your videos in Storyline, and the steps you have tried so far.

Here's an article that may help you ensure you have high-quality images and videos for your Storyline project. 

I suggest you start with a brand new .story file and move your project material there. Then try resaving with a new name and publish, and see if that does the trick.

Please let me know if you need additional assistance!
