Something’s not right there. If your other games are working fine, it must have something to do with your game version. I don’t have the Atomic Edition, but an old CD version I purchased >20 years ago, that contains Life’s a Beach and Duke it Out in DC. It’s not asking me for the CD, btw.
But the profile on this forum was made using the Atomic Edition, I think, so this shouldn’t be a problem. There haven’t been any changes to the game engine either that could cause such a slowdown. You should definitely try to get your hands on another copy.
