Modern Warfare 2 Beta stuck Checking for Updates? Here's how to fix it - Dot Esports

To find the Main folder inside Modern Warfare 2’s beta folder, players can right-click on the beta client on Steam, choose Properties, select Local Files, and click on Browse.

While PC players might be able to get through the Checking for Updates error, console players’ hands will be tied.

This error mainly appears on consoles when players fail to connect to the game’s servers, meaning their best option will be to restart their game and router to fix this error.
