Did you use a level 40 spark of light on your warlock before or after redeeming the code for your hunter?
yes i boosted my warlock a week ago but i thought you were able to buy 1 per class?
You should be able to buy one for each class, but once it's purchased for a class you can transfer it within game to any character. Just trying to figure out what might have happened. If the code can't be redeemed or was previously used, you'll have to contact amazon for a new code or a refund.
yeah i looked on amazon but they said that game codes cant be refunded or returned the code works it pulls up the hunter pack and says to redeem then it says error
"Error"? That's odd. If you're redeeming your code using a web browser, try using a different web browser, and/or making sure your pop up blockers are turned off. You could also check your console marketplace while logged into the account you purchased the spark for. I believe it would say for a level 40 Hunter pack, that it's not available for purchase, if you had already used one for your hunter.
