Hey mate,
I've been trying to get this working forever. My issue was not being able to unzip the file (mac osx, google chrome browser...)
Turns out the file shouldn't be a .zip at all. Some mac osx browsers throw the .zip on there (presumably having to do with mac hating everything adobe).
1) Make sure you have Adobe AIR installed
2) If it comes up as a .zip, rename it to .air (.air probably already exists right before the .zip, mac osx will prompt you to select .air as the final extension).
After doing this, it should be fine. Follow the video instructions from there for the port info (doing it now, hopefully it works.)
