Modern Warfare 3 beta “error in reading the current match rules”: Possible fixes, reasons, and more

Call of Duty: Modern Warfare 3 (MW3) is currently live for players in the second beta phase. Since its under testing, it could show up with a notification that says “There was an error in reading the current match rules data” while trying to queue for a match. This problem seems to be an issue that exists on the current platforms that host Modern Warfare 2 and Warzone as well.

Modern Warfare 3’s inclusion in the Call of Duty HQ would inherently bring some problems from the previous shooters. However, the developers are trying to minimize any issues that could potentially harm the community's gameplay experience. This is primarily done by gathering different game data from the title's beta phases. The issue might land on the developer’s radar soon since they are stress-testing the game and the server.

This article will highlight possible fixes for the failure in reading match rules data in Modern Warfare 3.

How to fix error in reading the current match rules data in Modern Warfare 3?

Here are a few methods that you can employ to get through this problem and play Call of Duty: Modern Warfare 3 (MW3) matches:

• Turn off your game and run a quick file integrity check to make sure all local files are functioning as they should. In case of missing files, the client will automatically download and install all the required items.
• A quick restart can also help the client establish a fresh session that would fire up all dependencies correctly.
• You can also try clearing the game cache files (on PC) and starting the game from scratch. This will allow the client to set up all the required files again in the background and might solve any underlying issues.

It is important to note that these are not official fixes but simple workarounds that may help avoid the issue till the developers release a patch to fix it. However, it seems to be a rare occurrence and does not appear for a large majority while queuing up for a match.

Possible reasons

Any online multiplayer title has a long list of moving parts that need to work in perfect sync or a system crash could occur. The error in reading the match rules data seems to show that the system could not identify which game mode is being queued for in the home menu. This would hint at the matchmaking and validation process missing out on the selection data made by the user.

Such an issue is usually deep-rooted in the game and cannot be solved by players. It would require the developer team at Sledgehammer Games to create a targeted update exclusive to this issue.
