I have gone through the game completely on easy mode. I went to start over and keep getting told I have to download plugin 2.3.1_125, which I don't need since I do single player and don't need voice comms ability. The plugin keeps telling me to install it and continue, but will not let me continue. I do save, then run, and it acts as if it is downloading and running, then nothing happens. This is the first time this game has done this to me. I have a PC, run Windows 7 Vista, and as I said before, have played through the entire game once, so it was working properly up to the introduction of this plugin.
