I've met the same error message.
It's a fresh installation of v1.3.8 with FedEx module http://www.zen-cart.com/index.php?ma...roducts_id=367
(with some changes from http://www.zen-cart.com/forum/showthread.php?t=82955)
I use phpinfo() to make sure cURL is enabled on my server:
cURL support enabled
cURL Information libcurl/7.18.2 zlib/1.2.3
However, this module returns following debug message
( I replace my personal info with xxx)

Then I tried to apply a Production Meter Number from FedEx website, but still get similar error.
Do I still miss something?
