Exporting Problem

I’ve created online portfolio in Flash and due to size, added a preloader. The preloader doesn’t really work, though, because it waits for all of the movie clips in the library to load. I deselected the option for “export in first frame” from one of the movie clips in order to test it. That particular movie clip didn’t load at all, even though “export for actionscript” was selected. Can anyone help me figure out how to fix this?

Thank you in advance.
