"unexpected file format" for FlashConversation.fla

Hi all,

I ran into this problem when I tried to run the example on Flash-Arduino.
I downloaded and extracted all the files. However, when I tried to open the FLASH file, FlashConversation.fla, I received this error:

"Unexpected File format."

My first guess was that my FLASH MX (2002) may be too old. So I upgraded it to MX 2004.
Still the same error.

Anyone know why?

Thanks in advance...
