I'm having the issue that the first post is refering to. I signed up for an account for the USPS Web Tools. I'm assuming this is the right account that I need. I can't seem to figure out if I need to do anything on the USPS end or not. I have all of the information in the OSC module entered correctly (I'm assuming, I do... I have production selected for the server to use). I e-mailed USPS to see if we are on the production server and I'm waiting on a reply. I also downloaded the latest usps.php from the CVS. I'm not really sure where to take this issue from here.
