I just bought pes 2008 for my pc. I inserted the disc into the drive and the installation process started. I agreed to the terms and conditions, but when I was asked for my registration code(which is on the back of the manual) I entered it but it wouldn't let me go onto the next stage of the installation process. I have double checked the code more times than I care to think about but each time the NEXT button that should be lit up isn't. The only options I am given are BACK or CANCEL. It is driving me crazy. The only explanation I could think of was that the code on the manual is wrong and does not match the game disc. I have contacted Konami but I was wondering has anybody else had this problem.
