I have been unable to get Nightlife that works on Vista but I just found one today in Double Deluxe. I also got Celebration stuff with that. Trouble is the third thing is Sims 2 basic game. Of course I already have that--so if I upload this exp pack, will it screw up my game? I've added other combination packs that had an expansion pack that I already had and it said do you want to skip this or something to that effect (Mansions and Gardens). But that was just an expansion pack, not the game itself.
