Showing you how to fix the COD Warzone error code PILUM

After many players have constantly been complaining about this error, we have decided to take a deeper look to see what are the reasons that cause the problem in the first place. Here is a shortlist that contains all the possible causes for this issue:

  • Simple bug – The missing package that causes this issue might not download due to a simple bug that is happening to your game. The game can’t make the connection to download the package automatically, so you have to manually search for it on the Microsoft Store. You can do this directly from your Xbox console, or you can use your personal computer to start the downloading process.
  • Problematic MAC address – This problem can also be caused by an erroneous Alternate MAC address, as it turns out. Several impacted customers have reported that removing the stored Alternate MAC address and restarting the console resolved the issue, allowing the machine to use the default MAC address.
  • Corrupted files – Another cause for this error could be some corrupted files that make the game not download every file that it needs. This is causing the packages to be missing, making the game unplayable. If you can’t find the missing packages anywhere, you should do a factory reset to get rid of the corrupted files. We recommend you keep your games and apps when you restart them.

Now that you are aware of all the possible causes of this error, here is a list of all the methods that players have used in order to fix this:

1. Download the Multiplayer Pack from the Microsoft Store

The first thing you should try that has helped many players fix their issues is to download the Multiplayer Pack directly from the Microsoft Store. This is an easy thing to do that was very efficient for the players that are going through the error code PILUM.

Fortunately for you, there are two ways that you can do in order to download the necessary packages.
