This project is invalid or corrupt and cannot be opened. It may have been created in an earlier version of Storyline problem

Hi Abdullah,

I'm really sorry to hear that you've run into a problem with the project files. The error message is indicating an element of corruption or latency associated with the file, and it's typically tied back to not adhering to the behaviors documented here. 

If the file has become corrupt, there may still be a working version of your project in your temp files. Here's how to check: 

1) Open this folder in Windows Explorer: %appdata%\Articulate\Storyline 

2) Scan the contents of this folder for a file that starts with the name of your project. If you find one, copy it to your desktop. If you find more than one, copy the latest version to your desktop. 

3) Change the file extension of the copy on your desktop from *.tmp to *.story. 

4) Double-click the file to open it in Storyline. 

File corruption is unpredictable, and there's no straightforward way to determine what causes it. Common causes are environmental (disk errors, power outages, improper shutdowns), viruses, failed Windows updates, and even file size (i.e., very large files have a higher risk of corrupting).
