WTH! STORYLINE 360 keeps just closing

Hi Steve, 

If you're able to publish files that your colleague is not able to publish, you can ask them to look at repairing Storyline. That's a good first step to ensure Storyline is working correctly. 

The C drive is typically a local drive, whereas a D drive is likely mapped to a network/shared server. That can lead to corruption or other odd behavior in project files as the file is syncing continuously in the background and could have issues with latency. You'll see this detailed more here (with some other best practices to prevent odd behavior). 

I know Crystal is testing a file of yours as well so hopefully, that'll narrow down some of your other odd behavior!
