Call Of Duty 2 Dvd Edition Problems

I just bought Call Of Duty 2 at a flea market. All the guy gave me was one dvd disc. After searching the net I found out it comes with 2 or something. But the second disc is just trailers or a movie on how they made the game from what I remember reading.

Anyways the install was fine. I installed the game off the dvd perfectly. But the game won't run single player. It will only run multi player. & I can't play multi player because I don't even know how and don't want to. So it beats the purpose of doing that. Plus multi player uses the internet & I don't have internet on that pc.

When I have the dvd disc in I try to click on the shortcut on the dektop for "single player", and all it says is an message "Cannot locate the DVD-ROM .... Please insert the correct DVD-ROM, select OK and restart application".

What the [bleep]? Did this guy rip me off and only give me one disc?

Darn. I mean this is the one I used to install it. & Like I said when I click "Multi Player" I get to the menu screen but I don't play because I don't know how to use "multi player" and I don't have the net on that pc. I have never used multi player on any game in my life.

I right clicked the dvd disc in my computer and it's size is: 3.53GB

Hope that helps.

Thank You.
