Native Context not available using Leapmotion AS3 ANE file - actionscript-3

Question

I´m getting this error while trying to compile a Flashdevelop AIR project:
Native Context not available. The Config class is only available in Adobe AIR.
My setup:
Using Starling.
Using the ANE file from https://github.com/logotype/LeapMotionAS3
Using Flex SDK 4.6.0/AIR 3.8 in Flashdevelop 4.4.4 RTM
Extended Desktop profile is on.
The error fires up when I try to use the controller.config() or screen.* as in:
if(leap.config().setFloat("Gesture.Swipe.MinLength", 200.0) && leap.config().setFloat("Gesture.Swipe.MinVelocity", 500)) leap.config().save();
My onConnect();
private function alConectar(event:LeapEvent):void{
trace("conectado");
leap.enableGesture(Gesture.TYPE_SWIPE);
leap.enableGesture(Gesture.TYPE_SCREEN_TAP);
if(leap.config().setFloat("Gesture.Swipe.MinLength", 200.0) && leap.config().setFloat("Gesture.Swipe.MinVelocity", 500)) leap.config().save();
if(leap.config().setFloat("Gesture.ScreenTap.MinForwardVelocity", 30.0) && leap.config().setFloat("Gesture.ScreenTap.HistorySeconds", .5) && leap.config().setFloat("Gesture.ScreenTap.MinDistance", 1.0)) leap.config().save();
//etc...
}

[Fault] exception, information=Error: Native Context not available. The Config class is only available in Adobe AIR.
Already change the bat/SetupSDK to: set FLEX_SDK=C:\Program Files\FlashDevelop\Tools\ascsdk to reflect the SDK (Thanks to Philippe from Flashdevelop).
Any help is welcome.
Regards!
