If you encounter these problems while playing MW2, it is likely that “Dev Error 11557” is the culprit. The good news is that there are ways to fix it.

One straightforward solution is to reinstall the game. This method can be tedious, especially if you have a slow internet connection, and depending on the game’s size. But if other methods fail, it might be the only way to go. To reinstall the game:

  1. Right-click on the game’s shortcut on your desktop.
  2. Select “Properties.”

To update your drivers:

  1. Go to your computer manufacturer’s website and download the drivers specific to your device.
