I got a card that did not display right. It gave that strange symbol like in one of the first screenshots in this thread.
I know you won't fix it right now, but I just wanted to let you know that when I right clicked it and selected to copy the link code or something, it said this:
http://allcards.bfreborn.com/cards/Protectors-Seal-(Twilight).jpg
So now you know that this card (protectors seal twilight) is not showing, and the other protectors seal probably has the same problem.
