Dynamic preload of images

I have been following this toturial http://www.kirupa.com/developer/flash8/video/loadingPicturesDyn.htm to preload images in my movie. Great video toturial!

My problem is though, an error occures when the loader component is loading content like so ( Error opening URL “[file:///D|/cebsone.dk/Ny%20mappe/cebs_003_.jpeg](file:///D|/cebsone.dk/Ny%20mappe/cebs_003_.jpeg)” ) Ive got the .fla file in the same folder as the images.

Im well aware that this toturial is for Flash 8 and I use Flash MX 04, so is there anything different about the dynamic preloader?

Any thoughts on what im doing wrong here?
