Error: This project won't open because it uses features that aren't available in this version of Storyline.  The features in use are:

Emphasis Animations

Install the latest Storyline update to open this project.

I AM using the the latest Storyline version.  I am not able to open the project to even delete or correct whatever emphasis animation for which the error is indicating.  All other project open without issue.
