Wow TCG loot cards not working.

I bought several WoW TCG packs this afternoon and was excited to find I got a couple more "landros gift" loot cards, after entering the code on the promotion page. Then visiting that lil swindler Landro in game and entering the code as usual, I got the message, " Validation code error please try again." so assuming i just entered the code incorrectly I tried again, same error.

Now to make sure it wasnt just a problem with the card, I scratched another one and entered it as well, then proceeded ingame and tried to redeem it, same error.


Can anyone explain what I might be doing wrong ? I did several of these the other night on the same server, and they each worked fine.
