Flash Builder 4.6 breaks iOS exporting with Air 3.6

Okay, my first question is, which version of the Air 3.6 SDK am I supposed to overlay onto the Flex 4.6 SDK? Is it the one WITH the Compiler on this page: http://www.adobe.com/devnet/air/air-sdk-download.html, or the one without the compiler? Or, am I supposed to use the one with the ASD2 compiler (or whatever it's called) for FB 4.7? I'm guessing not the last one...

Thing is, I've tried installing Air 3.6 with both of the abovementioned versions of the SDK - with and without the compiler. Whenever I try a new one, I delete the folder I've just installed, then start again.

I've tried:

- Overlaying Air 3.6 SDK (both versions) on top of fresh extractions of Flex SDK 4.6

- Overlaying Air 3.6 SDK (with compiler) on top of my old installation of Flex SDK 4.6 that originally had Air 3.2 SDK overlaid on it

- Overlaying every version of Air since 3.2 on top of my old installation of Flex SDK 4.6 with Air 3.2, up to 3.6 with the compiler

Everything I try, ends up in error messages when I try to export release build for iOS.

When I'm on Air 3.6 SDK, this prevents it:

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

When I switch back to Air 3.2 SDK, I get a blank error message:

"Error occurred while packaging the application: "

I have JRE 7 installed on my computer. Everyone is talking about JRE 1.6 or 1.7, but mine is 7 so I'm not sure how that's so far off...

I'm not sure how simply inserting a new SDK folder has actually *broken* the iOS export for past versions of the SDK - Air 3.2 USED to export to iOS just fine - it worked a few days ago before I tried upgrading.

In light of all this - where have I gone wrong? What do I do to fix this? Where can I download a fresh install of Flash Builder 4.6 so I can start from scratch and try again?

I have to get this working... I spent so much time builing my app to this point, to only have to now switch IDE's is going to slow me down significantly.

Thanks for any assistance.
