New installation error message trying to access admin section

Hello,

I just installed the newest version of Zen Cart, the root of the site is working correctly http://www.flipfloptreasures.com/test

however after installation where it gives you two options either to view store or admin section, when trying to go to the admin section I am receiving this error message:

Fatal error: Call to a member function Execute() on a non-object in /mnt/w0202/d05/s04/b02c422c/www/flipfloptreasures.com/test/admin/includes/init_includes/init_db_config_read.php on line 13

from the file: init_db_config_read.php

<?php

if (!defined('IS_ADMIN_FLAG')) {
die('Illegal Access');
}

please let me know what I need to do to fix this error so that we can continue setting up our store.

Sincerely,
David

It would seem that you're missing one or more files in your /includes/ folder.
Sometimes FTP programs encounter timeouts and leave files in incomplete states or missing altogether.
I suggest a full re-upload using an FTP program that will tell you when something fails to upload properly.
