What is the latest USPS module that should be working and usable?
I have switched to the live version and I still get an error. with the 4.1
What error are you getting?
What I get is that the priority mail medium flat rate box is not showing up.
However, the small and the large is there, and looks fine, charges appropriately.
The 4.2 USPS Module is now working!
