Preloader problem

I have a problem I really hope someone can help me with. I have made a flash-site with a preloader, but the preloader doesn´t show at once, and when it finaly does, it starts at about 40/50%
This is a big problem, because the screen is just blank, and you have to wait before the preloader appears… I have also unchecked the export in frame1 for movieclips, components and so on… :slight_smile:
