Do I need to change anything in the shipping files for USPS to work?

[Reenie]

USPS told me that they need to switch to production mode which they did, but this is still coming up.

Is there a green dot at the right of USPS??

Down near the bottom of the USPS module edit screen you need to select the USPS services you wish to use
