Wordpress Install Botch --- can't login NEED HELP

Cancelled

Job Description

I need someone who can figure out what the heck I did to this wordpress site. I was doing an install for a client and while editing the CSS I pasted something incorrectly. Then when I went to delete my mistake it gave me a warning and now I can't even access the /wp-admin page, all I get is a warning. I have tried accessing the site via ftp, but am unsure where to go from here.
