Problems after changing admin folder name

Hi...

I'm going through the steps of the tutorial and have changed my admin folder name and the recommended configure files. Now when I type the new admin folder name into my browser it bypasses the login page where I used to enter my admin name/password and goes right to the main admin page. What did I do wrong...and how do I get the log-in back?

Me again...well, I didn't change anything else, but now I can't access the admin main page at all????

The first issue could of been a browser/cache related issue ...

Not being able to get in at all ... well ... I'd start with checking the configure.php file in your admin on your server, and substitute the new admin directory name:
/admin/configure.php

check that this file contains all of the changes for the paths where all /admin are now your /new_admin_name ...
