Problems with 3.6 >> could not resolve s:ViewNavigatorApplication

Hi,

I'm trying to use 3.6 and not having any luck...

I have FB 4.7 (64-bit) on Windows.

I have downloaded from here; http://www.adobe.com/devnet/air/air-sdk-download.html

I have completed the steps here; http://helpx.adobe.com/flash-builder/kb/overlay-air-sdk-flash-builder.html

I have merged the sdk as I would have done for 3.5,3.4 etc.

Now, when I set the SDK to the 3.6 one, I get the error;

"Could not resolve <s:ViewNavigatorApplication> to a component implementation."

_MUST_ be something basic I'm doing wrong here!

Help!
