getURL not working - crossdomain?

Hi,

I developped a simple flash photoalbum, but since the project has gone live the links on the buttons are not working anymore.

The swf is located at http://client.ourdomain.com and if we test it like this it works fine. But if we go to http://www.client.com it goes wrong. The dynamic xml is loaded fine, images and text as well, but only the getURL stops working.

getURL("http://www.client.com/products/be-nl/121/listall/page/1/","_self");

anyone? Thx.
