Apologies if this is the wrong place to ask for help.

I have installed the SDKs, built the content, run the .bat files ...

When I load the index page, it gives a bunch of loading messages,
then I get the "Starting" message, and then I get this:

Loading data ... done.

Thanks if you could point me in the right direction. :-)

I figured out it is because
virtualGamePad
is null on line 2640 of http://192.168.1.80:8080/SampleFNA/bin/JSIL/Platformer2D,%20Version=1.0.0.0,%20Culture=neutral,%20PublicKeyToken=null.js

... hmmm.

This in turn seems to be happening because LoadContent is not being called.
And LoadContent is not being called because "flag" is false at line 14258:

var flag = (this._graphicsDeviceService !== null) &&
($IM02().Call(this._graphicsDeviceService, null) > null);
if (flag) {
this.LoadContent();
}

graphicsDeviceService (and GraphicsDevice) are both not null ... so it is this call to $IM02 which is returning false.

$IM02 is calling this:

function InterfaceMethod_CallInterface_I753$get_GraphicsDevice$void$eq619(thisReference, ga) {
if (!thisReference["I753$get_GraphicsDevice$void=619"])
this.$StaticMethodNotFound(thisReference, "I753$get_GraphicsDevice$void=619");
return thisReference"I753$get_GraphicsDevice$void=619";
};
return InterfaceMethod_CallInterface_I753$get_GraphicsDevice$void$eq619;
})
