Storyline Not Opening Older Files

Hello,

My co-worker and I are having an issue opening a Storyline file from 2024.

We open it, but then it just shows the main Storyline page without actually opening the file

Does this have to do with the latest update, or is there a glitch?

We update courses very frequently, so this puts on hold on any course we need to update

 

Thanks!

Erin
