I recently received CIVIV Gold edition for the holidays. I have been reading through the "abridged manual" which I find does not have answers to my questions about the game. The cover says "Full Manual on Disk 3" but when I go to open the data4.cab on Disk 3 I get a message "WinZip cannot open X:\data4.cab because it is not in the standard microsoft CAB format ...". So how do I open it and get the full manual?
