JinkyO,
To help you correct the issue with paypal we will need some help from someone more familiar with PayPal Express to find where to update the code to strip the unwanted extra characters from the state, not a difficult thing to do, but I really dont have the time to search the code to find it right now.

As for your other issue, did you turn on debugging for the mod? If so what did you get for output?
