Recover Original Storyboard Content -- 2

In 2014 storyboard was used to create reading lessons on my website: DezPhonicsIndia.com. Shortly after the lessons were uploaded to the website, the developer's hard drive crashed and he lost all the original content and the Storyboard program. The website contains all the code for the lessons. The website works fine with the lessons on an android but not on all platforms. It is a Wordpress website and all the "html", "swf", "mp3", and "png" files are in one folder on the website. Because the storyboard rendered the files in an "html + Flash" format, I want to "un-render" or "reverse engineering" the lessons back to its original format and then render the storyboard with html5 without the Flash. IS IT POSSIBLE TO RECOVER THE STORYBOARD FILES BACK TO IT'S ORIGINAL CONTENT? If it's Possible, then all I want is to recover the original content of Storyboard. The lessons are in one folder called 'lessons'. DO NOT MAKE CHANGES TO THE WEBSITE. Copy the 'lesson' folder and work from the copy. Save all the original content in a file and e-mail it to me. There are 50 lessons. Each lessons contains about 120 slides or frames, consisting of a background image, some animation, and an mp3 voice segment. If you need more information, just ask.
