intel starter pack

guys In my intel starter pack I got the halo wars 2 , but whenever I try to use the code it doesn’t work , any ideas ??

If you are having issues with redeeming the code, speaking to Xbox Live Support is the best way to go. They can validate the code for you and make sure it’s ok

I have the master key but can’t get the code. I got the message from intel website say “Temporarily out of inventory. Check back soon!” What can i do now??
please help.
