IE SCRIPT5 and access denied problem

Hi guys.

i have an issue with a jquery function. in IE appear SCRIPT5 and access denied errors, everything works fine on the others browsers, and i know exactly wich part is that make the error, if i take it, the page load normal, but if dont , i just get a blank page.  the bold text, is the part that i mentioned, and doesnt matter if i write .html() or .append().  some suggestions ? please.

This is the script :

$('.ca-item-main a').live('click', function(e){
e.preventDefault();
var href = $(this).attr('href');

UpdateProducto(href);
});
$('.nav a').live('click', function(e){
e.preventDefault();
var href = $(this).attr('href');

href = href.substr(href.indexOf('/') + 1);
var categoriaName = href.substr(0, href.indexOf('/'));

UpdateProducto(defaultProducto[categoriaName]);
UpdateCategoria(categoriaName);
});

function UpdateProducto(hrefLink){
var productoContent = "#producto";
$(productoContent).empty().append('<div id="productshow"><img class="loading" src="images/loading3.gif" /></div>');
$.ajax({
url: hrefLink,
success: function(data){
$(productoContent).empty().html(data);

if ((hrefLink.indexOf('-ptm') != -1)){
UpdateProducto2(hrefLink);
$('#productshow').css('height', 635);
} else {
$('#productshow').css('height', 535);
}







}
});
}

function UpdateCategoria(categoria){
var categoriaContent = "#categoriaslide";
$(categoriaContent).load("producto/slide-" + categoria + ".html");
}
});
