Problem getting Flash/Director animation to load in Internet Explorer [renamed]

I am SUPER new, so please don’t laugh at me…

I have created a VERY simple animation in MX2004 and placed it in an HTML file using Dreamweaver. When I visit it using Mozilla Firefox, it works fine. However, when I visit the site using Internet Explorer, it shows the Macromedia Shockwave “loadin bar looking” screen and never loads and doesn’t display the animation. Please help me, I’m dumb! Thanks!
