Hi Starlet, it was really not a good idea to necro this thread, the reality of the game has drastically changed in these 10 years, maybe go through the sticky posts, or open a separate thread with questions if you want to be taken seriously.
2 basic infos for you:
Ubisoft doesn't any longer support this game, neither Ubisoft offers his online server for it. You must play the game through U-Play.
Then, the stock game updated to 1.2.0 alone is not a functional game, it needs heavy modding. As a shortcut to this, read about the 'The Wolfes of Steel' mod for the game, this is the only acceptable way to play for newcommers.
Good luck
