Flash (AS3) and Arduino connection

I am in urgent use to connect Flash CS4 (Action Script 3) to Arduino IDE 0013. I use this tutorial: http://protolab.pbwiki.com/TutorialFlashSetup2009

I have a problem as described in the 4th item of tutorial's troubleshooting section. And I did what the solution tells me to do. But it didn't work. Still can't see the "Firmware version: 2" message.

Any suggestion or solution? Thanks so much.
