Deadpool

Hi, I'm having trouble loading the BCM demo after i have installed it. I got the demo off the coverdisk in pc gamer, i've read the FAQ and says that i need to obtain a serial number after installing it then get an unlock code from 3000ad to play the game. I can't seem to find a serial number of any kind, i apologise if i'm making an abvious mistake but would appreicate any help as i would like to play the demo, cheers.
