Index.html doesn't work, "use application to open"

(solved) i made a website for me. when i open my site : http://rzakyn.com

it says : use application to open
application/x-httpd-php

it doesn’t open index.html automatically. how can i do that?

here is my html : http://rzakyn.com/index.html

this works fine.

how can i point out to preloader.swf, instead of index.html, when i type rzakyn.com. this can be a solution too.

original code was with php. but my server doesn’t have php. so i modified some. but manually writing index.html works fine as i said above.

thanks
