trying to buy points for premium with a us bank card(visa), but every time i try it says transaction couldn't be processed(doesn't give a reason why). i have enough money on the card and my information is correct. do i need to use another service for us player, and if so... which one? thank you, gankfest™ p.s. i looked in the knowledge base, payment stickies, faq... i don't know where else to look, and hope this is the right place to post this.
