I just switched host and went live with my site. Now when I try to access my catalog I get sent to a system setup required page. I am assuming this is the problem but have no idea how to remedy it. PLEASE HELP

Your /includes/configure.php and/or /admin/includes/configure.php file contains invalid path information and/or invalid database-connection information.
If you recently edited your configure.php files for any reason, or maybe moved your site to a different folder or different server, then you'll need to review and update all your settings to the correct values for your server.
