Unable to get to Dashboard – wp_admin file in wrong location?

After installing WP, I’m stuck. I cannot access wp_admin. Here are the highlights…

From cPanel, I chose to install via Fantastico, and perhaps I missed something in the instructions & video (which were for WP 2.7, alas).

When I was done, I clicked on the Visit Site link. At the bottom of my browser I see this:

https://creativelynostalgic.com

Of course, the site displays a generic message telling visitors that the domain was recently purchased, and the site is being created for the domain, etc.

When I use FileMagager to look at my home dir, and see this:

(/home/lmiller)
access-logs
etc
mail
public_ftp
public_html
tmp
www

I see the wp_admin folder in two places: in the public_html & www subdirectories
In both cases, the folders look like this:
wp_admin
css
images
includes
js
maint
network
user

So it looks like the wp-admin files are installed in the wrong place perhaps. This is what I get for trying to do too much in one evening. Kind of embarrassing, since part of my day job is supporting a web application.

Any advice onfixing this is appreciated.
Thanks
