marketpress shipping plugin just ships US domestic when residential is clicked

Hi there,

the fedex plugin was always saying: no service available.

I´m pretty sure my customers will not even try the 10 times I did to get a setting that gives them a quote.

Now my question: Is there a way to turn on debugging for shipping?

Another note: The shipping plugin doesn´t get updated when User types in a new zip code. It just happens on the radio and select buttons.
