Error message when viewing HTML5 on IE10

Hello,

I have a simulation created in Captivate 6 and publisged in HTML5. I have incorporated the HTML5 output into a Lectora file, published as SCORM and loaded to our LMS. When I try to view the Captivate simulation, I get an error message that states "The browser does not support some of the content in the file you are trying to use. Use one of the following broswers: Internet Explorer 9 or above." However, I was on Internet Explorere 10 when I got the message. Any ideas?

Thanks!
