Unable to buy backwards comp games on xbox one

I've been getting the message

"Sorry, Your purchase cannot be completed at this time. Please try again."

When trying to buy Modern warfare 2 on both the xbox one store, and trying to buy it on the xbox store from my pc. All I could find on fixing it was to buy it on an xbox 360, I don't have an xbox 360 so is there any other ways to fix this so I can buy the
game.

Tom Clancy's EndWar for Back Compat

I love all the Tom Clancy games. One I would like to see come to Backwards Comp is Ghost Warrior. End war is pretty awesome too. The Backwards Comp list is still growing every week. One I waited for a while was Crysis 3 and they finally added it to the list.
Keep an eye on the full list here

$99 Xbox 360 on Black Friday

There is 0 reason to buy a 360 on black friday when the Xbox One is offering lots of backward compatible games and that library will continue to get bigger.

Do yourself a favor, buy an Xbox One, buy 1 yr of Xbox Live Gold and enjoy 4 free games a month, 2 from 360 backward comp list and 2 XB1 games.

Then you can buy the newest games with 360 classics.

 

There is currently a service alert up for purchases - Xbox Live Service Status | Xbox Live Service Outage

If that resolves and you still have issues, if you're on a child account, you'll need to make the purchase from a 360. Otherwise, make sure you have a credit card or paypal on file to make the purchase.

 

So when that is cleared up it should work?

Considering I do have a card on file and it isn't a child account.

Thank you for the response!
