Hello everyone,

Using Zen Cart 1.39h and the May 26 version of this module.

We had problems from the beginning. First, I was told I could not connect to the the testing server.

When I registered with USPS, the confirmation email told me to use a different dll for the testing server (shippingAPITest.dll instead of shippingAPI.dll), so I changed the dll name on line 682 and we started connecting.

Now, I'm getting "RateV4 is not a valid API name for this protocol" errors.

For reference, I started with the January 2011 version of this module and received the exact same error with RateV3.

Any suggestions?

Beth
