Help wanted, Quick Install WP Error!

Alright, I just got a hostgator account for my domains, and want to use wordpress for the sites. I used the "Quick Install" in cPanel, clicked on Wordpress, and I got this error message.

"Error: The chosen directory must be empty or non-existent before installation can proceed."

Anyone understand why it would say this?

Ok, now it says it installed it, so I go back into "Quick Install" and up to Manage Installations. It displays that Wordpress is currently installed to the site. So then I click on it, it asks me for blog title and email, and then has a button on the bottom that says Install Wordpress (but I thought I just installed it!) Then I click on that, it gives a huge page of error messages, but then at the very bottom it says "Success" and gives me the username and password info, with a button underneath that says "Log In"

What do I do after that? I hit the button and all that happens is that I'm returned to the same page that asks me for blog title and email, and then has a button on the bottom that says Install Wordpress! So I just keep going around in circles!

Edit

Ok, problem solved. I got on chat with tech support and he had to change some files around. That's one thing out of the way, now off to whatever else!
