regarding about your concern why this occurs in IE and not in chrome, that's because of this condition if(/MSIE/.test(navigator.userAgent) which is true when your browser is IE

for correcting the issue, as you said in a ment you can add a 'undefined' condition.
just replace this line:

if(/MSIE/.test(navigator.userAgent)){Element.setStyle(_10,{filter:Element.getStyle(_10,"filter").replace(/alpha\([^\)]*\)/gi,"")+"alpha(opacity="+_11*100+")"});}  

with:

if(/MSIE/.test(navigator.userAgent)){var filterStyle=Element.getStyle(_10,"filter");if(typeof(filterStyle)!="undefined"){Element.setStyle(_10,{filter:filterStyle.replace(/alpha\([^\)]*\)/gi,"")+"alpha(opacity="+_11*100+")"});}}

and this line:

if(/MSIE/.test(navigator.userAgent)){Element.setStyle(_10,{filter:Element.getStyle(_10,"filter").replace(/alpha\([^\)]*\)/gi,"")});}

with:

if(/MSIE/.test(navigator.userAgent)){var filterStyle=Element.getStyle(_10,"filter");if(typeof(filterStyle)!="undefined"){Element.setStyle(_10,{filter:filterStyle.replace(/alpha\([^\)]*\)/gi,"")});}}

in the effects.js file

Open developer tools in IE (press F12) and click the "Console" tab. You should be able to see in there that there's an error with the effects.js script :

SCRIPT5007: Unable to get value of the property 'replace': object is null or undefined 
effects.js, line 1 character 1747

That should at least give you somewhere to start looking.

...and if you're that lazy, the actual line of code it's failing on is this :

Element.getStyle(_10,"filter").replace(/alpha\([^\)]*\)/gi,"")

The getStyle call is clearly returning null, so subsequently calling replace will fail.

Internet Explorer does not currently have full HTML5 support. Any manipulation of HTML5 related tags or elements will therefore fail. It is worth trying to include the html5shiv library, which tricks IE into believing these tags exist.
