Game problems

Hi, I have 4MB internet in my house, but after todays patch, I cant play this game normal any more. It is totally unplayable. I shoot at someone, right at his head, waste whole round and still make no damage to that person. Instead, he kills me with one shot. Than, when I throw bomb it stays in my hand for more than five seconds and than go who knows where. Other players move in very weird way- they stay in one place for a long time, and, in the next second, they disappears. Than, when I go to one room, it shows me that game is currently being played, but, when I enter, all players are still waiting game to start and pressing start button makes no difference, like no one had pressed it. I am sorry to say but this game really begins to sucks.
