How can I add a pre-loader to an existing complex flash project

I have a pretty complex flash project that I need to add a pre-loader to.

Currently all the items we have are in the Library inside the .fla file. I've been reading a few of the pre-loader blog entries and tutorials and getting nowhere.

I've tried to create another .fla file that loads the compiled .swf file of the complex project and that did not work as well.

This is my first flash project and I'm pretty inexperienced with it. What do I need to do?

Do I have to strip all the items from the library and load them individually (and have them saved somewhere on a server) ?

How can I create a loader class wit开发者_StackOverflow社区hin the project that runs on Frame 1 and "Loads" all the items that are needed?

You can probably make a loader class within the existing project that loads everything in the first frame if needed. Its pretty dirty design-wise, but can work.
