I got the game. It's fun.
I just finished the GDI campaign and i'm wondering what would the bad ending would've been like. 
Did you try reinstalling the game ?

What error ?I can't play the GDI campaign (the game shuts itself down when I click on it and an error message appears). What could be the problem?

If they don't, ask for an exchange. If one CD is faulty, then the next one shouldn't be... right? Or you could defrag your hard drive I guess or something, try seeing if it's a hardware problem
