Hi, I downloaded/installed the SDK - this time using the IDE packager (from SVN) and was able to compile and run application for iPhone, iPad and Android with no issues.
It possible that the SDK I was using didn't have the AIR SDK as the URL were broken at some point. If I get some time I'll take a look over the weekend. Thanks, Justin BTW The IDE packager compiles (to a dmg) installs and run fine on a Mac.
