I’m trying to load an external .swf using UILoader. If the .swf doesn’t have any code, it loads fine. But if I add any code, even only comments. It gives me this error.

```auto
 
TypeError: Error #1009: Cannot access a property or method of a null object reference.
 at main_fla::MainTimeline/__setProp_BackgroundLoader_Scene1_BG_0()
 at main_fla::MainTimeline()
