Has anyone used Lancelot's free AdMob ANE?

Hi all,

We are trying to incorporate AdMob into an AIR for Android app developed in Flash Pro CS6. We'd rather avoid paying for the Milkman ANE if possible, so we tested out the Lancelot Mobile ANE from http://lancelotmobile.com/blog/admob-ane/  . The instructions are for Flex, but since we aren't using a Flex app we were trying to implement it in Flash Pro - however, CS6 won't publish the document, instead reporting the ANE file isn't valid. Any thoughts? There are enough people reporting it working in the comments there that it's hard to believe the ANE is fundementally broken, but I'm at a loss as to what to try next.
