Project is invalid or corrupt and cannot be opened By Courtney Archer Hi all, Please help! We are getting the following error when opening Storyline files: "This project is invalid or corrupt and cannot be opened. It may have been created in an earlier version of Storyline." The file was saved to our shared drive. I am unable to open it from there. I am also unable to open it after moving the file to my desktop. Please save us from having to constantly rebuild. Thanks so much in advance.
