big mistake when trying to create config. file

Please help me!

I was asked to help the gamers over at elitearenas.tk (a Gaming Ladder) with simple customization like buton colors, etc. I thought ‘piece of cake, I’ll go in and do some simple HTNL codes make the font the color they want, whatever. Done’. NO. The site had to simeple HTML editor except for when editing the rules. I was given access to the site owner’s account on the host site (bighosted.com). I was wondering around and I figured I needed to add some kind of HTML editor to the site. I found a WordPress 2.7 installation…installation thing. I got past installing it then I got stuck on making a configuration file. When I couldn’t firgure out what to do I decided to go the file manager and delete the WordPress files. BIG MISTAKE. Just before, when I installed WordPress and members went to the site it was a black page that said the configuration file needed to be done. Then after deleting all the WP files the page was nothin but a blank white page.

Please, Please help me, I’m way in over my head, and I really don’t want toruin these gamers’ ladder!!!! (They’ll have to buy a new one and it’ll be all my pathetic-self’s fault!!)
