The forum has delt with this issue before, but after reading the relevant posts I haven't been able to find a resolution. After losing my old copy of SFC II, I bought another copy last week. However, the CD key required to launch the game will not work. I have already tried exchanging copies, entering all the different permutations, etc, but nothing has worked. I also emailed Interplay from their support page but have not heard back from them. I am running windows XP, so maybe that is the problem. In any event, I love SFCII and cannot wait to play it again. So if anyone has found an answer to my problem, any advice would be greatly appreciated. Thanks.
