I didn't realize Storyline wasn't backwards compatible, and I foolishly updated the software mid-project. I now can't open my files. I tried reinstalling each older version available in the Articulate 360 desktop app, but each version still gave me the "older version" error when I tried to open any files. I hadn't used Storyline in a while, so I'm not sure how old the version on my machine actually was before I updated. Not more than a year, I believe. Is it possible to access older versions than the six previous versions available in the 360 desktop app? Or is there a way to somehow unlock an older file? I'm in a very big pickle. Thank you!
