Command and Conquer Generals, China Mission 7

I have been playing Command and Conquer for many years. I have the complete CD ROM collection. And I just recently got a new gamming computer (laptop) with no CD ROM, and I had to download the EA app to punch in my codes so that I could play without the disc's. Since then, the China mission 7 is missing a lot of material! It is missing the way up the hill on the left side to the oil derricks plus it's missing the snippers that i could rescue and use along with the 2 spies in the radio stations! How can I get all of that back? Thank you for your time!
