I’m trying to play zombies on call of duty and it says i need the season pass, Even though i have it already? Anybody know how to fix this or have this issue??
Right you need to go to the store, and actually click on the Havoc DLC pack to download it, If you have done that then say, and i can help you get online. 
What the guy said below, Go to store and install map pack - It might say Buy it but when you select it it will say you already own this would you like to install content
Got it thanks! 
Good, now there is another way in which you have to get onto zombies, which is easy, if it comes to it, Ask and we shall reveal (the answers)… ;D
