Flash + Arduino ALMOST WORKING!

(followed this whole tutorial: http://www.codingcolor.com/as3/arduino-flash-as3-part-4/)

When I test it in Flash, the outliner instantly says: “Socked Connected! Socked Closed!”

My Terminal running TinkerProxy says: "Failed to open comm port – connection refused"

Any idea what’s going wrong here?

Thanks in advance!
