Error messages / error codes
For all your questions about error messages / error codes, we kindly request you to view this Blizzard page. We would like to inform you that we can under no circumstances offer you help in finding out the meaning of certain error messages / error codes.
Do you get an error message saying that your code has already been used? As soon as we have received the payment, your code will be activated (= made usable) and delivered immediately. This makes it technically impossible for your code to be already used before you received it. This error is probably a technical issue that happened when you redeemed the code the first time. The steps below can sometimes help to solve this problem.
- Make sure you have redeemed the code on the correct account (for example, you redeemed the code on account A while logged in with account B).
- Check the transaction history of the account where you redeemed the code.
- Restart the device and log in again. This ensures that your credit is updated.
Is the problem not solved after this? Then please contact the publisher.
