I applied for the preview program when I bought my Xbox one on launch. Received the code for the preview program, but did not enter the code. Now I am trying to get into the Battlefield 4 CTE and it seems I need to be in the preview program to do so. I spoke to Xbox customer support and it was explained to me that messages sent through Xbox live are deleted after 30 days. Please if possible re-send my code so I can input it properly.
