Help! I pre-ordered Cod infinite warfare digital deluxe edition but I got an error code and ...

Is it a game disc or digital game pre-ordered online?

If game disc, there should be a beta game code but for a limited time and also from the participating retailers only

If digital pre-purchase/pre-order, you should be eligible already. Kindly check this link.

COD Infinite Warfare Beta Faq

Hey there reddaro,

Since this is a disc copy and not a digital download of the Call of Duty Infinite Warfare, the console looks for the specific disc to know that you have the license for Call of Duty 4 Remastered according to Activision's support page

HERE.

"Xbox One

For disc-based (physical) Legacy and Legacy Pro Editions of Infinite Warfare on Xbox One, Call of Duty: Modern Warfare Remastered is included on the Infinite Warfare disc and no voucher code is required.
Before Modern Warfare Remastered can be played, an additional download is required. An internet connection is required to download content. The game disc must be inserted to play Modern Warfare Remastered.

For Digital Legacy and Digital Deluxe Editions of Infinite Warfare on Xbox One, there is no game disc or voucher code. An internet connection is required to download content. Modern Warfare Remastered and Infinite Warfare
are two separate downloads and there is no requirement to have both installed in order to play either piece of content. No game disc is required if you purchased the Digital Legacy or Digital Deluxe Edition of Infinite Warfare."

So unfortunately it looks like you'll need to purchase the Legacy or Legacy Pro edition via a disc or Digital Legacy or Digital Deluxe to be able to play Modern Warfare Remastered again. Though you might fall under Activision's Disc Replacement program

HERE. It's worth taking a look to see if you qualify for that program.

I hope that helps and answered your question!

I am also having the same problem. I pre-ordered the digital deluxe edition 2-17-16 and it is the end of March 4th, but no code in sight. Help wanted please.

Hi Russell! I'm Rostom, an Independent Advisor. I will be glad to help you here.

There's no direct upgrade for your pre-ordered edition. You must cancel the pre-order of Standard Edition and pre-order the Digital Deluxe Edition.

Please go to your order history https://account.microsoft.com/billing/orders/ to cancel it.

Is it a digital pre-order or a game disc from a retailer? Kindly check this link about the beta game.

Game discs should come with the beta codes.

Digital pre-orders/pre-purchases will be eligible already for the beta game. No codes required.
