I got this simple XML Banner Rotator from oxylusflash. When I unzipped the XML Banner Rotator, I got the following files:

test folder
source folder
..caurina folder
..oxylus folder
....banner folder

I opened the index.fla file (provided by oxylusflash). copied the "banner" movie clip or the frame containing the "banner" to my flash project. My flash movie that will include your XML banner is called carousel.fla

I moved everything so it's in the same folder:

..banners folder

Error -- "1152: A conflict exists with inherited definition flash.displayisplayObject.mask in namespace public."

What did I do wrong?
