Problem : Visa $25 Gift Card Use

Does this website have a problem accepting gift cards? I've already registered it in my name and attempted to purchase a game with both paypal and direct input of the card information. It doesn't seem to accept it and the card has been used to make another purchase in another game just fine after registration. So, someone please answer if this is a "Impossible to do" scenario and why to me or an answer if you have one. It's a basic gift-card, purchased around the time of Valentine's Day Feb 14th, 2011, in the US. So, squeebles....

Some card companies do not allow transactions outside the US with gift cards.

Well, I called Customer Service today, and found out that the US tidbit is true. I did however read the entire TOS and the little pamphlet/container they sold the card in and could not find a shred of this otherwise important information. So no Might & Magic VIII for me. CUUUURSE YOU GIFTCARD PEOPLES! May the wrath of Bazooka Joe's ABC Gum Army make you suffer.... with horrible 2-second comics!
