These older sims do become more and more difficult to install as time marches on. For the time being I've given up getting MA to run as it won't load anything, not even the 2D menu screen.

As I notice you're running Win98, my installation tips might not work for you as they were intended for XP.

The CD drive on my previous computer wouldn't even recognize the FCG disc.

You should have mail JRT; a file called update, perhaps this is what is needed to get FCG going again
