No idea how to run CoD

[Jujuuk68]

Hi - how did you buy the game? Online or from box content?

I bought a collectors edition recently, and do have Steam pre installed. When I loaded the dvd rom for CLOD, it automatically detected it was a steam game. I did get a warning from the compatibility manager asking if the game installed correctly, and just ignored it til it had clearly installed. When the game fully installed from the Dvd, it then looked itself up on steam and downloaded an additional fairly hefty patch that took several minutes. After that, it was for me, good to go.

Have you got steam installed, and has the game patched itself prior to you running it for the first time?
