@devilsangel7190 Which expansion pack isn't showing up in-game? If your computer runs the Legacy Edition and you've downloaded Discover University or Tiny Living, the problem is that neither pack runs in the LE. If your computer cannot in fact run the standard version of Sims 4 and needs the LE instead, you can request a refund from EA customer support.

If you're missing a different pack, or you're not playing the Legacy Edition, let me know.
