I am a fairly computer dumb, new Civ4 player. I have been playing the game just fine until I searched for updates and it suggested to install a patch, 174 i think? then when I tried to open the game it says "the program can't start because D3DX9_32.DLL is missing from your computer, try reinstalling the program to fix this problem." However, when I go to the add remove programs it will not let me uninstall the program to reinstall. it says " Error {5004 : 0x80041f42} has occurred while running the setup. Please make sure you have finished any previous setup and closed all other applications"? Help!! I feel like an idiot here. I love this game and now I've screwed it up???
