Preloader problem

Hi! I’m working with Flash MX 2004 and I desperately need to know how to do my preloader.

I usually used a preloader on another scene but here no preloader on the same scene or another works. Someone told me it was because of the attachmovie(). So when I start the preloader, it takes great time before it goes to the first frame. All is white. So I wondered if an external preloader would do the job or would still do the same thing!!! Please help me!!! hihihi? Do I seem desperate enough?

If you think an external preloader would work, please tell me how to do one!!!

Thanks a lot!!!
