Storyline issues to save the work

Yes, you have corrupt files (videos, audios, etc) in the project.

Try to import everything into a brand-new project.

Hi AgnesAponte-101,

Thanks for reaching out and I'm sorry to hear you've hit this snag!

I see you've connected with my teammate, Lejan, in a support case. We'll continue the conversation there. 

If anyone in the community is experiencing a similar issue, you can try importing your slides into a new Storyline project as Tianxuan suggested. It's also a good idea to work and save your project on your local hard drive (typically your C: drive). I hope this helps!
