Cannot run some games

I have downloaded some games but I cannot run them.

I downloaded Civilization IV, I installed it, but when I double clic it in the Applications window a message appears: "Please insert the original disc".

The same happened to me with The Movies game.

Please help! what do I do to play them?

Wrong forum, wrong site buddy

you buy them

As was pointed out by the replies you received, those were illegal downloads. (pirating) We do not discuss illegal activities in these forums.
