Well, if the website you are talking is the one on your profile, your website seams to be working. I got the front page, clicking on the image brought me to the index of page which was empty. So you should be set. Probably it was not finish propagating across the net yet.
As you may be aware, your front page and the subdomain are two separate folders. Your domain folder and the subdomain folder will be sister folders below your root folder. So backing out of your domain folder you should see the subdomain folder.
