Delete Steam Download Cache

First, open up your Steam launcher. Click on Steam on the top left of this window to access your settings.

In the Downloads section of your settings, click on Clear Download Cache. This will delete your Steam download cache and you will be required to log back into your Steam account when this is done.

Steam Settings > Downloads > Clear Download Cache

Verify the Integrity of Modern Warfare 2 Files

After logging back in, navigate to your Steam library. Right-click Modern Warfare 2 and select Properties. In the Local Files section, click on Verify integrity of game files. This will take a minute to redownload and replace any missing or corrupted game files that could trigger the disconnected from Steam error.

Modern Warfare 2 > Properties > Local Files

Disable VPN Connection

While verifying your game files, open up your Windows settings. Here, under Network & internet, select VPN and ensure your VPN connection is currently disabled. A VPN can, in some cases, prevent you from starting the game correctly. If you are looking for a reliable VPN connection, we recommend PrivadoVPN.

Command Prompt

Lastly, if the problem persists, open up your command prompt by searching for CMD and hitting enter.

Here, use the command ipconfig /flushdns. This will flush and reset the content of your DNS resolver cache. After launching the game, disable the On-Demand Texture Streaming option to prevent this error from occurring.

This error can be caused by a variety of reasons including network connectivity issues, outdated Steam client, or incorrect game files.
To fix this error, you can try resetting your internet connection, updating your Steam client, or verifying the game files in the Steam client library.
