HTML_5.story file not playing in Internet Explorer 11

Need some help my customer moved to Internet Explorer 11 and now the Articulate Storyline project will no longer work? (this is not storyline 2)
The html.story file opens but my links only work with the html_5.story file. The html_5.story file will open and the circular "wait" icon spins around then goes away, but nothing shows up?
Is there an issue with explorer 11? Alternatively, is there a fix for my issue?

Thank you in advance,
