Domain help

Hello everybody,

I need your help:
Problem: when someone clicks my http://www.worldtravelshop.biz there comes a default index.html, which is installed when I created the new webhosting site.

Install: I installed wp in http://www.worldtravelshop.biz/wordpress

The server info is that I should replace the index.html, with my own.
But my wp installation does not have a index.html OR how can I solve that problem? Please tell me.

Thx
Eric
