i can't get modern warfare to stop having loading issues

First, try to power cycle your console, and remove and re-add your profile.

If the issue persists, I would recommend trying these troubleshooting steps:

Settings > Network Settings > Advanced Settings > Alternate Mac Address > Clear

If the issue still persists, please select System > Settings > devices and streaming > blue ray > persistent storage > clear three times > restart console.

If the issue keeps on happening, it’s possible that the local save for your game has become corrupted. If so, you might want to delete the local save to re-sync with the cloud, it might correct the problem.

I have loads of issues with Modern Warfare and doing a hard reset of the Xbox or unplugging it for a few minutes fixes it for a while.

Did they remove the quote post thing? I can't seem to find it.

Anyways, "Why do you think its called MW3 and not Modern Warfare 3" this is where I stopped reading. It is in fact called Modern Warfare 3, MW3 is just an abbreviation.

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.

Hello,

You may have to uninstall some packs from your game. Check out this thread and see if it solves the issue: Modern warfare is not loading me in a match - Microsoft Community

Thank you,
