code looks fine...
can you do something...
put a print statement after function new() and see whether the program is reaching that scene..

Tested it and it gets to next scene before I get the error.

I can't regenerate the error...
can you try commenting the lines with SetReferencePoint let's see what happens.

What do you mean?

I commented the lines and now it doesn't give an error but:

The reference point is wrong.

When it switches scene and you got back to it, the time text jumps away and it is there for more than 3 seconds.

        end
        
        timer.performWithDelay( 3000, onTimer,1)
        
        startTimer()
        return localGroup
end

The problem is that the timer doesn't stop quickly enough.

Got it working with http://jonbeebe.tumblr.com/post/2439016279/how-to-use-the-new-time-functions

Now i got a game.cancelAllTimers() right before the director:changeScene("mainmenu")

Thank god for Jonathan Beebe :D
