Fatal error: Call to undefined function genesis_theme()

I installed the Genesis theme but forgot to install the other supporting Genesis theme module. Now all I get is this message below and I cant get to my admin screen to change the theme. I tried this http://drupal.org/node/332634 and changed my 'theme' record to Garland in phpMyAdmin under the root and secondary account and still nothing.

Can someone please tell me how can fix this problem I seriously need to get this back up.
