Xbox code redeemed but not by me

My point is I went to redeem the code on the xbox and it told me to redeem it on the website. So I went to redeem it on the website and it told me to redeem it on the Xbox. When my friend gave me his spare code his worked immediately.

That's pretty crazy. I redeemed mine on my Xbox and it worked fine. I just clicked the code and it took me to redeem a code screen with the entered code.

Only keys for Office 365 Home/Business edition can be redeemed that way. The message prompts me to redeem my code on Xbox:

"Xbox. Please redeem this code on your console."

Thank you anyway.

You cannot redeem the code from the Xbox live home (dashboard) to redeem the code you must select redeem code in Madden 13 itself. I believe you can go into the settings and do it, although it gave me the update to redeem the code instantaneously after I
signed in with my hard drive in the game itself.

The 14-day trials tend to have expiration dates and generally don't work if you've previously had (or currently have) a full Xbox Live membership. If you check the fine print on the card itself you might find reference to this.

Now that you've redeemed a different code you'd be unable to redeem the original one at least until the current one expires, depending on the terms of that original code.
