To install or reinstall WP, that is the question..

I had coding issues earlier, and ended up following someone else instructions on another forum, and was able to get into my FTP file manager. I deleted all files except Apache logs and Error logs, as it won’t let me delete those. But when I go to the cPanel in my GoDaddy account and try to install WordPress again, I do see the “Install WordPress” botton, but now its saying dbalentine.com is already in use, and wants a directory.

What’s the directory?

How can I install or reinstall WordPress?
