I found the marketing text in:
wp-content\nerocity\themes\

sidebar-front-page-header-first.php
sidebar-front-page-header-second.php
sidebar-front-page-header-third.php

footer text:
sidebar-footer-first.php
sidebar-footer-second.php
sidebar-footer-third.php

Just manually delete the text from there.

I had the same problem after the upgrade to 2.9.1 hung. Fixed it pretty easily, thanks to others who had the same problem. I downloaded 2.9.1 to my computer, and then deleted wp-admin and wp-includes on the server. I uploaded the root files and the wp-admin and wp-includes folder. After that it worked. I also could go into the control panel. It warned me that the database needed updating, and that worked quickly without issues. Thanks!
