Flash can't open example file

Hi,

I'm a newbe and I've just got a Arduino and I'm getting myself familiar with it. I'd like to connect to Flash MX2004. I can get Kaspar Lamperman's example swf to work but I can't open the fla file? Any thoughts or ugestions would be greately appreciated.

I worked it out. Flash MX2004 is too old to open the file but I opened it in Flash CS3 and copied the text and pasted it into MX2004 and got the important part working straight away.
