Okay so like 4 years ago when Wh40K Dawn of War was released for the PC, I was one of the first people to buy it. However, at the time, since the game was new only a few people actually played in the online mode, so I soon lost interest and went back to playing Star Craft, until I got CS:S... Anyway, now I've gotten interested again, and have re-installed Dawn of War, but there have since been 3 game updates... Winter Assault, Dark Crusade, and Soulstorm. These updates combined cost more than the original game itself, and don't seem to even need the original which I have anyway.

So, I was wondering if anyone could explain which one(s?) I need to get to have everything set up properly.
