Flash CC and google display network clickTAG

Question

I have been trying to add a clickTAG to my advert files in Flash CC. Seems to work fine but google is rejecting the adverts as an 'unsupported format'. It appears that Google will only accept SWF files up to 10.1 and the lowest you can export in CC is 10.3. I have downloaded 10.1 encoder and added it to the program XML files but still not accepting. My last hope was to open in CS5 or CS6 and that should work but I can't seem to be able to backsave or I don't know how. Any advice on this? The clickTAG I am using is below:
btn.addEventListener(MouseEvent.MOUSE_DOWN, onClick);
function onClick(e:MouseEvent):void {
          var click_url:String = root.loaderInfo.parameters.clickTAG;
          navigateToURL(new URLRequest(click_url), '_blank');

Answer 1

I got it sorted... finally. I had found a link that explained hpw to add 10.1 but the info was not 100% correct, another guy had it right for 10.2 so I just went through the 10.2 code with a fine tooth comb and changed it over and it is working now.
For anybody who is looking, and I am not a coding person, far from it, this is what I done.
(1) Downloaded the 10.1 playerglobal.swc from Adobe here.
(2) Right mouse click (or ctl click on a mac) on the Flash folder and show package contents - then click Contents/Common/Configuration/ActionScript 3.0/
(3) Create a folder called FP10.1 and drop in the downloaded file (should be called playerglobal.swc).
(3) Go back to the common folder and go to Common/Configuration/Players
(4) Duplicate the FlashPlayer10_3.xml as FlashPlayer10_1.xml and open this file in textedit or whatever editor you have and replace the text with this:
<?xml version="1.0" encoding="UTF-8"?>

(5) close and restart flash
(6) Pick 10.1 in your export settings and it will work now.
Seriously, thanks to all who tried to help, Adobe should really fix this issue as its a pain for people who are not developers and code is alien to them.
