Yup that should be the option I meant. Are you forced to enter country and name there, or can you click continue without them? And are you sure you are using the right email address that the nds-card guys sent you? I guess if Paypal does not know the email address at all it asks for additional data, at least I remember something like that.
Maybe an American user can shine in, but at least here in Europe Paypal does not ask any additional things (well except the amount of course) when you enter a valid paypal registrated email address unter "Pay for goods or services".
Don't feel bad, Paypal is a nightmare from the UI point of view

This is nothing compared to searching the options for paying in other currencies without paypal fixing the exchange rate, its hidden so deep that it takes easily an hour to find it.
