I have a SWF file, and it accesses an XML file. It works just fine when debugged or published into a standalone SWF. HOWEVER, when I add a preloader to it, I get the following error, every single time:  
**TypeError: Error #1009: Cannot access a property or method of a null object reference.**

It works just fine when running on it’s own, but when it runs through a preloader, it will not work.

Has anyone had this problem before?
