Nevermind, just got it to work. I had to use another pre-paid card (Portugal has a nice system called MB Net, it allows you to generate a pre-paid card and use it on the go but the one I was using was goofed up apparently. Either way, if I don't spend the cash on a pre-paid card it'll be thrown back into my bank account so that's what'll happen to the one I tried to use before.)
