Ok Maybe I am losing it here but need some help!

I had installed this mod a few weeks ago, It was working, or so I thought.

Then I started having trouble with the address information not coming across to USPS and I gave up cause I was under the gun to get the shipments to the PO. The next day it still did not work so I reinstalled the mod. Tryed it with one or 2 boaxes and it worked fine. Went to use it last night as I had 27 shipments to create and it did not work again.

Noticed this morning why I think it is not working...
It seems to only be working with orders placed on my site today, orders from yesterday or 2 days ago do not work. It does not carry the address information over for those orders. Did I do something wrong? If so what could I have done?? If anyone can help me I would be so greatful! I think this is an AWSOME mod and a HUGE timesaver for me, once I can get it working right ;)

Thanks!
