Now when I type

www.mydomain/catalog/my_new_admin_name

I am getting zen cart page which says
Hello. Thank you for loading Zen Cart™.
You are seeing this page for one or more reasons:
1.This is your first time using Zen Cart™ and you haven't yet completed the normal Installation procedure.
If this is the case for you, you will need to upload the "zc_install" folder using your FTP program, and then run zc_install/index.php via your browser (or reload this page to see a link to it).


2.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.
See the Online FAQ and Tutorials area on the Zen Cart™ website for assistance.
The first reason is not possible..coz I went through all the installation process and reached to the stage where it said access /login to admin panel at the end. But when I clicked on that it asked me make few changes which I did and since then nothing is happening.

Now, about the 2nd point, I have checked multiple times and the content of of that file is fine...but then why are things not moving forward from here ? and why am I not able to access the admin area ?
