TestCase Login / FAIL .. Manual Login / Pass .. Need Help

To Whom Can Help:

This is my second project using soapUI so I'm relatively new to it, but I feel I'm adequate.

I'm having trouble logging into a Magento website to be able to test the wishlist and checkout process.

Going through the soapUI interface manually:
I enter my login credentials
Click "Login"
I get logged right in immediately

So I tried to emulate this functionality by sending the login credentials (using POST) to the form "action". Not only does this take 2 minutes every single time, it also fails every time. It sends me to the Magento must have cookies enabled page.

I have the "Manage HTTP session" option checked.

I'm using soapUI 4.0.0

Any ideas?
