Server rentals :: NFOservers.com

What I did to fix my issue was:

1. I went in and deleted everything about the server
2. went in and created everything again
3. when auto-installing, I made sure that it didn't install to a folder
4. deleted and recreated the database

after doing all those steps the website worked

I just cleared my cache... now I am getting this

Warning: require(/usr/www/nsbgttt/public/wp-includes/load.php): failed to open stream: No such file or directory in /usr/www/nsbgttt/public/wp-settings.php on line 21

Fatal error: require(): Failed opening required '/usr/www/nsbgttt/public/wp ...

When trying to load my site, I get a page telling me "No website is currently set up at this address."

when I add /wordpress to the end of the URL, I get the actual page... How did I screw up, and how can I fix this issue?
