My shiny new copy of PES6 PC arrived today. I tried to install it but for some reason my dvd drive wont read the disc!! I have been playing WE9 for ages with no problem, I also downloaded the demo of PES6 which runs fine. Why cant I install the game on my computer? Am I missing something here? Ive been waiting for 2 weeks for my game to come in the mail and now its here I cant get it to install...please help.
