The version of Zen Cart I am using is 1.3.9d. I'm having trouble with the usps module. I was playing around with the module before I realized I need to register for the webtools. I registered with them and received a password and username. I plugged in my username in the id place no place for password? and filled in the other required information. I don't understand what I am suppose to do. do I need to reinstall the usps module & how would I do that? Do I have to do something with the test or production? I called usps number and I was asking questions and the guy just said we dont provide zen cart help. The usps email said to test on 2 links but when i tried they were bad links. I would appreciate any help. Thanks
