Why wont my Chartboost ads work?

I purchased the Chartboost Plugin and set everything up on the Chartboost side of everything. Here is my code:

    local function adListener( event )         if ( event.isError ) then             display.newText( sceneGroup, event.response, \_CX, \_CY - 100, \_FONT, 18 )                     end         if ( event.phase == "init" ) then  -- Successful initialization             -- Pre-load the "more apps" screen             chartboost.load( "interstitial" )         elseif ( event.phase == "loaded" ) then             display.newText( sceneGroup, "loaded", \_CX, \_CY + 100, \_FONT, 18 )         end         display.newText( sceneGroup, "in function", \_CX, \_CY + 200, \_FONT, 18 )     end     chartboost.init( adListener, { appId = "\*\*\*\*\*\*\*", appSig = "\*\*\*\*\*\*\*\*" } )

Chartboost is definitely imported in this scene, and it’s properly in the build settings. I call 

chartboost.show( "interstitial" )

 when the character dies, but the function is never called. I have added texts so I can see the messages on my phone, but none ever show up. Thanks for any help.

Just kidding. I figured it out already. I was testing on Android and it notes on the documentation that you need to use the latest daily build. So anybody who has this issue, just download the latest version of Corna Simulator.
