Resaving version 5 to MX2004

I saved a file built in Flash 5 several years back. I believe I used portions from a tutorial here. I have a scene of a vertical scrollbar controlling an external text file. It is working flawlessly online as version 5 but not in MX2004. I made no alterations to the scene and can see no problems with the AS. Fairly new to MX2004 though.

The slider in the scrollbar doesn’t move but the up/down arrows do scroll the text. I also see that the text appears different eventhough the properties appear to be correct.

I have uploaded just this file (extracted from a scene) to explain my case. Any help would be greatly appreciated.
