Game does not start or has an error when it attempts to start

America’s Army uses Microsoft DirectX®. It is possible you may have an issue with DirectX that was caused during the installation of another game or program. Make sure you have the latest version of DirectX installed on the computer. Additional information about DirectX can be found at http://www.microsoft.com/windows/directx/default.aspx

Make sure all other programs are closed when you attempt to run the game.

If computer is over clocked try reducing the speed back to the computers correct settings to ensure that the over clocked settings are not causing the issue.

If the above does not resolve your issues you can try uninstalling the game and deleting the America’s Army folder. Restart your computer and then reinstall the game.
