Hello, I purchased the old counter strike game, not the new condition zero and not the new half life 2. I bought the old one- it's in a black and yellow box. It's this one- http://www.gamestop.com/product.asp?product_id=644096 . The game tells me to update because I have a 18.104.22.168 version. My friend said I need 1.6 Steam. I don't know where I can download the new patch to play the game. I tried multiplayer online but it didn't work because I had an old version, they told me to download the new patch. Anyways, what is a Steam? Where do I download to get my update so I can play multiplayer online? I'm scared to download some things because I heard that some people can steal my CD-Key. Thanks in advance.
