fiddler will work for you but you have to unsecure your facebook account from facebook settings .... I mean use facebook as http instead of https
then u have to clear cash from browser
after that open fiddler and open the game
wait untill swf file shown to you, and right click> copy> just URL
now open autoresponder tap and click enable auto resposes and unmatched requests
then press add... the url will be added
next step is in rule editor in the same tap... last one "local file to return or action"
press on it and press "find a file..."
now browse for the hacked swf file
and press save
now clean the cash again "u have to!!"
and refresh the game
and good luck
btw if u are in a high level 44 and up don't use it cause maybe u will get suspended for ever!! it happend to me :\ but if ur yard not very good so you will not lose alot try it
