USPS did not show as an option

I use zen cart v1.3.8. I am trying to offer usps shipping to my site. I have done the neccessary registration for webtools and have everything set to production. When I ran a test from my site, usps shipping did not show up as an option. Do I need to upgrade zen cart or re-install the usps shipping module?

Did you get the January 22, 2012 USPS upgrade from post #1 ...

Make sure that you have installed that and followed the instructions ... then to test, go to the Tools ... Developers Tool Kit ... and do a search on:
usps.php

what comes up in the version id?

Make sure that you did the:
REMOVE
load the new version with FTP
INSTALL
re-configure

Do I need to upgrade ...?

Regardless of USPS ... yes you NEED to upgrade. Your site has security vulnerabilities.

Where do I find the USPS upgrade and how do I instal it? How do I upgrade my zen cart to 1.5 version? Please someone help me. Thanks
