Installed a new script and now I can't see my webpage?

[jzstrato45]

I had originally installed PHPNuke for my website, but then I uninstalled it and installed Drupal instead using Fantastico. But when I tried to visit my site, it came up with the cgi error default web page. Link to my site is
http://www.prominence.exofire.net/
Any help?
