SPRY menu bar not working in IE 9

Question

Hey! I recently just finished building my very first website using Dreamweaver CS5.5!  It looks really great and works perfectly in firefox and safari however the SPRY menu bar does not work in IE 8 or 9. Does anyone know what i can do to fix this without messing up how the website looks in firefox and safari?
thanks,
Toby

SpryMenuBar.js
This file handles the JavaScript for Spry Menu Bar.  You should have no need
to edit this file.  Some highlights of the MenuBar object is that timers are
used to keep submenus from showing up until the user has hovered over the parent
menu item for some time, as well as a timer for when they leave a submenu to keep
showing that submenu until the timer fires.

            <p>Integrated Sensors is the first company in the world to apply the high gain, high-performance advantages of low cost PDP-TV (plasma display panel) technology to radiation detection.   This has resulted in the development of what is now known as the Plasma Panel Sensor (PPS), which has been called a <em>revolutionary</em> technology by U.S. government scientists. </p>
            <p>Integrated Sensors with seven issued patents holds all of the core intellectual property - which is seminal in scope - on the PPS radiation detector technology.  The PPS could well prove to be a transformational technology for a number of <em>multibillion</em> dollar industries, ranging from radiation therapeutics for the treatment of cancer, to medical imaging, to homeland security. </p>
            <p>With a secure IP and patent position established, and an international collaborative team involving over a dozen world-class scientists, and with substantial research investment by the U.S. government, Integration Sensors is now transitioning to the commercialization of its technology.</p>
