USPS AutoFill mod is not working?

I was just informed by the shipping staff that the usps auto fill mod is not working, anybody else having this issue? It seems that the usps site was upgraded, any thoughts?

Vanilla v1.5.1

Had you seen this?

No, I guess we need to install the new mod :(

this applies to click-n-ship one that worked with TY package tracker?

Apologies in advance for being dense, but I don't pull the rates from USPS since I use flat rate shipping, and I do use the USPS Autofill plugin -- it is not working. Are you implying that these mods are dependent on each other?

I'm at a loss.
I can do some programming but I have not been able to establish why it is no longer working.
My inquiries to USPS tech staff have gotten me no where as all they will say is "We can't help you in anyway as we do not support that functionality".
The mod stopped functioning after USPS did their last major Click N Ship site upgrade.
When I asked for help last week they asked me for the XML script that we were using so I am wondering if they switched.
Anyone have any insight with this so I can move forward with fixing the mod?

I looked at the problem with USPS Autofill back in the January/February timeframe. The issue (for the plugin, anyway) is that USPS has gone from a simple HTML form input to a (relatively convoluted) Ajax/jQuery interface that doesn't lend itself to "form stuffing".
