Preloader and Transition for Dynamic Files Tutorial

I have followed the tutorial and everything works great, in tutorial fla. When I try to apply the tutorial to a new fla, I cannot get the “opening” to work, the swf’s are loading because when I click on a new button, I can see them briefly under the transition, but my transition won’t open after load.

Its probably a stupid mistake, I don’t know where it could be, I’ve scoured all the actionscript for typos, I would think it would be in the actions for the content mc, but now I’m just frustrated.
