Preloader ****in up my contact page

I used a simple kirupa preloader to test my contact page which is two frames. One frame for filling out name, mail, subject, submit and another you get to see when the contact info is sent.

But when i use the preloader, i dont get to see the second frame to tell me the info is sent. Does anyone have a clue what the problem is?
And no i didnt **** up the code, cause when i remove the preloader my contact swf is working again.

Anyway, you can find my contact fla here.
