Hey there, are you having an issue that we can help with, if so please let us know what is going on.

Hello Ricardo,

Thanks for posting on the Xbox forums. We understand that you are getting an error message when you try to redeem a prepaid code for 14 days of Xbox Live Gold. Is the prepaid code for a free trial of Xbox Live Gold? Have you had Xbox Live Gold active
on your account in the past? A free trail for Xbox Live Gold cannot be used if you have had Xbox Live Gold on your account before. If this is not the case, we suggest
reaching out to Xbox Support. You can choose to live chat with an agent if you would like immediate assistance. Be sure to let us know the results
Ricardo!

Hello FellHaddock1099,

Thank you for bringing this issue to our attention. Have you used Xbox Live Gold on the account that the prepaid code is being redeemed on? The reason we ask is due to the fact that Xbox Live Gold trials cannot be redeemed on an account that has used Xbox
Live Gold before. Be sure to let us know the results!

I have the same problem in that I was given a two free day trial when I purchased Fifa 16 and cannot redeem the 25 character code as it comes up with "you have a gold membership already" when I know my Xbox live ran out on the 01/12/15 and today's date is
12/12/15 so I am really annoyed that I cannot redeem my code
