Storyline 3 - Preview & Publishing Error

Hi Everyone, 

I work in a team of 7 developers who use storyline 3 for development. We have been using storyline 3 for about a year now and have no similar issues. Unfortunately, as of a few weeks ago we started receiving errors when trying to publish and preview (slide, scene, project). I've read a few discussion posts where the issue was caused from corrupt files within the storyline project; however, I'm using the exact same files that worked fine a couple of weeks ago (I was able to preview, publish etc. without getting an error message). 

Going through ~100 storyline projects that WERE fine and trying to find "newly corrupted" slides/files isn't really feasible in meeting development deadlines. Although it is a work around, it would really slow down production time. I welcome any feedback and would love to submit a sample project to a storyline tech upon provision of a secure link for uploading. 

Thank you in advance for your help!
