Simple Catch Pro slider not working on IE9

I have clients complaining all of a sudden that the Simple Catch Pro slider is no longer working in IE9.  This has been functioning fine, but has stopped working.  All cache has been cleared.  Another symptom along with the slider not changing images is that I can no longer see my default background texture as well as the dard footer background is gone. When I switch to IE9 compatibility mode, it gets restored, but all did work well in IE9 native.  Also, everything is working in Chrome. What can be going on and what can be done? Thanks! Shawn
