When the game starts wait for your mouse cursor to disappear and press the "WIN' key on your keyboard.
Run the "EA_Invasion_Inputs.exe" then go back into the game. (I'd put a shortcut for both
ArcCabView_Launcher.exe and EA_Invasion_Inputs.exe on the desktop. When you go to your desktop navigate to
EA_Invasion_Inputs.exe and press enter to start it then go back to the game.
It should now be working. If your mouse is tuck in the top left corner you need to close everything and
start again. You didn't wait long enough to start the "EA_Invasion_Inputs.exe".
