Won't download code error?

I received the same error code, but when I type it into the error code roster, it claims its and unknown error code.

I have overwatch on disc and It won't start, the rest of the games I have are downloaded and those won't start up either.

It won't even download for me. I get and error screen but no error code? C'mon Xbox and Microsoft whats the deal

Step 1 Once you've received your code thru messages from Xbox Live, sign in on your account on www.Xbox.com

Step 2 Click on your name and go down to messages, open the message from xbox showing your code.

Step 3 RIGHT CLICK the message where the code is and hit OPEN IN NEW TAB

Step 4 Should pop up with the title and give you the option to redeem, then go to your xbox and over to the ready to install list and you should see Halo Wars Definitive Edition ready to install, make sure you start the installation as it's not automatic.

Step 5 For PC, follow these steps then go into the Microsoft store on PC, go to Halo wars 2, download it, then click manage. There should be a list of things that shows and one will be HW DE with an option to download.

Wait so if this happens a redemption code from the store will or won't work? I just got this error code when they downlOade the new xbox patch

Maybe I didn't make myself clear:
