Trying to Start Fresh

Well, had a wp-website I was working on and I decided to use a “pre packaged” site. My site is called howtogetridoflegfat.org. With the help of the host gator tech I got the following error message:

Warning: require(/home/vulcan95/public_html/wp-includes/load.php) [function.require]: failed to open stream: No such file or directory in /home/vulcan95/public_html/wp-settings.php on line 21

Fatal error: require() [function.require]: Failed opening required ‘/home/vulcan95/public_html/wp-includes/load.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/vulcan95/public_html/wp-settings.php on line 21

Where do I go from here? Help!
