Installed Autofocus pro incorrectly and now can’t login!

I just upgraded to Autofocus Pro, and guess I didn’t follow the instructions correctly. I was trying to alter the functions manually by copying and pasting the php code myself, and now I can’t log into my WP blog at all.

I’m on the phone with GoDaddy customer support to try to delete the file completely, but it has not been found. I can’t log in, the blog is not found and this is the error message”

Warning: require_once(/home/content/76/5628276/html/wp-content/themes/autofocus/thematic-functions.php) [function.require-once]: failed to open stream: No such file or directory in /home/content/76/5628276/html/wp-content/themes/autofocus/functions.php on line 803

Ugh! Help me, please!
