Customer cannot login, redirected back to login page

[BHenderson]

Im stumped

I can create customer accounts all day long, but when I attempt to login as a returning customer, the page flashes briefly and brings me back to the login page. If I have items in my cart and attempt to login to checkout it does the same as before, but also dumps my cart too.

Im running on:

IIS 5.0
MySQL 4.1.9
PHP 4.3.10

site is http://www.4trm.com/catalog/index.php

Any help would be GREAT!!!

Does anyone have any idea to help me? I cant for the life of me figure out why this is happening. I can go into the admin side and see that they have logged in but, the customer still gets thrown back to the login page and dumps his/her shopping cart. This is the one thing that is keeping me from going live with this, and it has begun to drive me nuts

here is my catalog/includes/configure.php file.
