Invalid or corrupt storyline (created in an earlier version)

Hi Jamie,

Do you see the corruption occur after a certain point in time or after adding in any specific items? A few other tips are outlined here about file naming/paths and leaving Storyline open for extended periods of time. I'd also confirm that your local drive isn't synced to a cloud/server for storage, for example like a local install of Dropbox still acts as a shared server. 

If you need our Support Team to take a look at your files, we're happy too! You can upload them here and the team will delete them when they're done troubleshooting.
