Deeply confused regarding patches.

[Leutnant_von_Hausman]

I bought the English version of the game, and am currently enjoying the singleplayer, but am also enjoying the multiplayer.

In multiplayer, however, I get frequent lock-ups and crashes, meaning I am rarely able to finish a game. I am currently running the straight-out-of-the-box version of the game.

Now, I've heard that there are patches, but I'm not sure:

a) where to get them from
b) what they do
c) how many there are
d) whether I need to install all of them

I also heard that there is a multiplayer patch, or something, but that downloading this somehow screws up singleplayer?

I would appreciate any feedback and help. I can't seem to get onto the digitalthingy forums at the moment.. They seem to be down..
