Closed Captions Editor not Loading

Thanks Joe.  I did open a case and am working with Cleo to try and rectify this.  I've done a complete uninstall, clean up, deleted all old temp files and a fresh install and still it's the same.  I did find a log that indicates a failure to load the ffmpeg app upon load of the captions editor so I updated that app and reset my environment variables which has now got the editor to launch eventually after multiple relaunch attempts until it finally applies but it's not 100% by a long stretch.  But at least it gave me a chance to finish off my clients project.
