You are using Edge Animate 1.5 therefore it doesn't run with Internet Explorer 11.
You have to customize your html page (index.html) using Notepad (Microsoft) or TextEdit (Apple).
You copy and paste: <meta http-equiv="X-UA-Compatible" content="IE=10">
to the head tag.
Moreover, you can also add: <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
It's really a problem in IE 11, as it appears to work in 10 and below as far as I can tell through www.browserstack's website. I created the site in Dreamweaver. The Edge online instructions says they fixed the IE 11 issue and it should at least show the poster instead of the animation. I opened and re-saved the animation in Edge CC 2014 like they suggested but it still did not fix the issue. I'm not even seeing the poster. I'll try what you suggest, but I'll be adding the code through Dreamweaver...assuming that is ok.
That worked, thank you!!!! But now I'm noticing that IE is putting a border around the "login" button. Ugh!
