This project is invalid or corrupt......

Hi Cleona, 

I'm sorry to hear you ran into this. If you weren't using powerpoint at all, that error message is even more vexxing. When did you run into the error message? 

Another option for recovering a corrupt file is to look in the temp files and see if there is a copy there. 

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. Some common causes and preventative steps are detailed here.
