I just tried to install the Fedex webservices module by numinix and it is not working.

this page .../index.php?main_page=checkout_shipping is now completely blank when I go through checkout.
If I turn off the module in my admin the checkout works perfectly.

I have zc 1.3.9 php 5.2.17

I got the auth. key, password, and all that info from fedex and modified my files.

I'm not sure what I have done wrong. I would greatly appreciate any help.

Thank you.
