Main site kicks in before preloader

[rockinruler.007]

Hi,

I am desperately in need of help for my college website.
I have created the site, its a bit large > 4.1 mb and it has an external preloader.

The problem is, before the preloader completes, i.e. before the main site is actually loaded (I used the Simulate Download option to check), the main site itself starts playing with lags, with the preloader still on screen.

I tried to use the same preloaded on another external swf and it works fine, so the problem has to be with my main site swf but I can't figure it out.

I've uploaded the entire source on my server in two files.
The first one just contains the published files with the source of the preloaded, and the second one contains the source of the main file separately as it's a little huge.

I'm sorry about the files being large.
Please look on if you can, I've been shouted at once by my teachers for late submission of the prototype, I'll be in a worse mess this time.

Thanks a lot for viewing the thread,
Elbee.
