Cant play imported family because im missing expansions?

Vampyfan2

So i found one of my old saved families from my external harddrives, i copied it over to my new computer under the saves, but when i try to load it, it wont let me. It says that the saved game is with expansion packs that arent currently installed...trouble is, i have every stuff and expansion pack now...so will I be able to play them? Help please!
