Seems my code is broken. Tried entering it many different ways just to be sure. No luck. Seems that the code is either invalid or not registered yet. Anyone having this issue?  
 
it is really just another kick in the balls for me since I was really wanting to get the canteen since I am playing through on hardcore mode first... Sigh... Just another way to shaft me with this game. 
 
EDIT: oh yeah the important part, PS3. Also what worries me is in the fine print they have instructions what to do in case the code doesn't work. Which for some reason yields no results. Screwed. 
 
EDITING THE EDIT: Download worked.... So now I have to ask... anyone found out how to use the canteen?

yeah my codes not working either however im sure tomorrow mid afternoon ill try and it should work. 

Maybe the codes aren't active yet.

It's possible they haven't been activated yet, 
Or and this is a common gamestop move..... 
 
How many digits is your code? 
Gamestop is famous for sending PS3 codes with 360 pre orders, And vice versa.

Or it could be the fact that Microsoft gained the lead on New Vegas DLC exclusives and told Gamestop to cut off all Sony pre-order codes.

" Maybe the codes aren't active yet. "

I have the 360 version and it worked fine at midnight as soon as it came out.
 
Good luck guys.

So I played well into the morning. Loving the game. Just regained consciousness and entered in the code. It worked! Wait... what's that? 
     
 
French version? if it works then it works....

maybe the codes activate on the 22nd, which is the worldwide release date.
