I have C3C and everyone else in the game is C3. According to the readme file in C3C in order to play PTW with people who are not C3C, I have to browse to the folder where PTW is on my machine and run the exe.

Problem is that everytime I try and do it, It tells me to reinsert the cd and start over. Very frustrating. Anyone know what is going on?

Thanks!

Wait - you have Conquests? When you load the game up, select New Game, and your settings, and brings you to the Civilization choice screen, how many civilizations are there? There *should* be 31, and one Random button, even with a default Conquests install.
