Internal error caused by USPS Shipping Module, How to resolve it?

[transtor]

Yesterday i posted a thread mentioned that we encountered a 500 Internal Error after clicking the paypal button to checkout.

Before moving to godady, everything, including the payment and the shipping module, is OK.
Last week we moved to godaddy. and we got the 500 Internal error.
Now we found out the problem was caused by the USPS Shipping Module.
Last night we disabled the USPS shipping method. we can click the paypal botton to check out using other shipping methods. The checkout process went through smoothly.
However, once we enable the USPS shipping method, we would receive the 500 error after click the paypal botton to checkout.
So we can drew conclusion that USPS should be responsible for the error. Correct?

Then i contacted the USPS Webtool Rep, she told me my user ID passed the test, and the production as well. Everything are OK at their terminal.

Now what on earth is the problem from? How can I resolve it? I am familiar with USPS' service. SO usps is a MUST!

Thanks.
