Just wait. You have many more technical problems ahead of you with the COD Deluxe package. You will learn to hate the phrase: "Dead entity is not an object." I had to skip past half of a map because it would not allow me to climb down a ladder I had to get down to accomplish a required task. And after finally finishing the game, having reloaded the last level about 30 times to get through it without dying, a glitch prevented the concluding cut scene from playing.
When I encountered these problems I Googled extensively and searched Aspyr's website and was unable to find any solutions that worked for me.
Good luck, and if you haven't already, get COD2. It's a much smoother ride.
