Error when publishing a Storyline 360 course.

Hi Matthew, 

Sorry to hear that you ran into issues with publishing your Storyline 360 project. I'm glad to help out!

My initial thought is that you might be referencing a file in your course that Storyline 360 is unable to access or reach, based on the error message below: 

<Message>Empty path name is not legal.</Message>

Are you working locally when making changes and publishing your project file? If not, please try to move your project file somewhere on your C: drive before attempting to republish it. You can also check for any empty file paths in your triggers and everyone else that you have a directory declared. 

If the issue persists: 

• Try importing your slides over to a new project file
• Share your project file here or in private through a support case so we can take a look at what's happening

Hope this helps!
