Transition between External SWF's

I did the “Transition between External SWF’s” tutorial and it was great - easy to follow and it worked! However I am having problem with one thing and I’m not sure if it’s possible or not.

I put a menu bar for my website on the main timeline with a blank movieclip container to load the external swf files into. This worked fine, but then I have one swf that has a link to a photo gallery swf file and loads into the same window but no longer has the main menu bar on it. I want to have a “back to projects” button on this file that takes you back to the last swf. The button works and takes you back but it no longer has the menu bar from the main timeline on it. Is there a way to load both swf’s?
Your help is really really appreciated!
