whenever I try to install Rollercoaster Tycoon Deluxe or Emperor Rise of the Middle Kingdom, I get a message during installation that says to "enter disk 0 that contains the file Data3.cap". What is this? Why is it missing? And how can I get it back? Please help me. Beause of this I cannot install any games on my computer. I was told that it is a computer file and that I can download it somewhere but I have been unable to find it anywhere. I am desperate, please help. Thank you.
