On modern warfare 2 I brought the digital version but it's telling me to purchase it again...

You do not understand the issue, you have to understand that there is modern warfare (not free) and modern warfare war zone (free)

For those who have a physical version, we can't access the original modern warfare campaign and other stuff from the main game that we purchased, we can only access modern warfare war zone, everytime we try to play the original modern warfare and not modern
warfare war zone it tell us that we have to purchase it. Even though we had paid for the physical version already.

It should be in your ready to install if it was the digital version of the game. Or follow the steps here https://support.activision.com/mode...c-ghost-bundle-for-modern-warfare-and-warzone

same with mine too, I got the full modern warfare disc, but it's telling me to purchase modern warfare, but only giving me the option to play warzone.

I bought the digital version of ‘Modern Warfare’ and in the offline mode, it shows ‘Buy Modern Warfare’ in place of ‘Campaign’. Activision must do something about this
