1. I own modern warfare and I download besides multiplayer. Ive tried downloading...

Hi Connor! Let's work on this one.

What exactly is the device or console model are you using? Can I please have the exact error message you got there?

If you own the Xbox disc of Modern Warfare you would not be able to play the same content such as campaign and multiplayer on PC, without purchasing it on PC. Modern Warfare Warzone however is free to play and you can download and still play crossplay
on PC.

Sorry its my own fault, the download is clearly marked as ‘ Add on’ and I completly missed that part. Doh! Sorted by downloading the original game. Thanks

But, Ive been playing Modern Warfare for a couple of months and took a rest to play something else but when I went back to MC it asked me to download 3 of the 4 parts but when I clicked on those parts they were all ticked as downloaded. Ive cleaned the
desk thoroughly but still can only play Warfare part. Any ideas?

Ensure you have all the downloads once again. Modern Warfare has a lot of multiplayer, campaign, and data packs you need to download to even play the game.

I searched and downloaded all missing packs once, and still did not work. I went to manage and made sure all packs are there such as campaign 1 and 2, multiplayer 1 and 2, and spec ops 1 and 2.

It is for Modern Warfare 3, any other game I can download the updates, I have tried, but Mode Warfare 3 doesnt want to download
