Problems Loading RSS Feed From Another Site

I seem to have a problem here, loading an RSS feed from an external site

Here is my code

xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
//xmlData.load(“http://www.anime-expo.org/?q=rss.xml”);
xmlData.load(“http://www.animenewsnetwork.com/newsfeed/rss.xml”);

As you can see I am trying to load an rss.xml file from that site.
But it does not load it.
I have my ticker on http://www.eskalix.com/anime_news_ticker.html

do i need to change the script access for it to be able to load an xml file from another site?

If i publish the file locally on my computer and it loads the external xml file, but as soon as i place it on another site, it does not work.
