Hi, I have a problem to make purchases on cod aw has every I want to buy the DLC Havoc when lbought ca puts
me "buy this Obara" and that I have too depensser on the walk xbox while
I havestrictly nothing purchased.What is it you please

I downloaded the same CoD Aw havoc dlc pack and I have a couple hundred in the account so that's not the problem but I got a status code 8018101E. Downloaded to %95 and stopped. It said the download was incomplete. So I went to download history to resume.
As soon as I selected the dlc the screen returned home and now there is no dlc content. So pretty much it wants me to buy it again yet I was already billed for it via my card.

I as well have problems with COD Advanced Warfare. Purchased the season pass and some DLC add ons on Xbox 360 . Just got Xbox one and the AW game for one and season pass and DLC add ons say installed on the Xbox one but cannot access any.

Also thought the Havoc DLC was free to season pass holders but I too get to pay £11.59 for it.

Wish someone could help here - very much appreciated

Season pass and DLC add ons all say installed via AW Game and Xbox store.

I got the exact same message trying to purchase havoc dlc

took me 2 days to download digital pro edition advanced warfare which has all dlc , season pass , game and advanced arsenals, when it downloaded finally it still wouldnt show up in game you have to go into MY GAMES/APPS go to the havoc dlc press option
button delete and reinstall it worked for me. better buying from cod aw store
