Welcome to the forum maymay381.
There is a program you can run before you start your game that allows you to play whatever espansions you want by simply clicking the expansion "off". You can not "turn off" the base game with this program. You can find it
here . To download this program, if you are not a member, they request you register at their site. The tool you will get once you download the program, asks you to choose what expansions you want then you save it before you start your game.
