Application problem

I have a Flash game on Facebook, It decided not to display anymore for some reason. The app works on its own webpage fine. I know FB breaks things sometimes, but this is not one of those times. I need someone who can FTP to my site and look through the files to see if there is any reason why it is no longer displaying, and if so fix it. Someone with Facebook experience. The Flash Part of the Game is fine, i believe it has to do with the PHP scripts.
