Lost SIMS 3[Mac] [ Edited ]

[Killerbob71]

I downloaded SIMS 3 from GameTree many years ago. It was running fine on my daughters MacBook, but after a reinstall it is now gone. Hence I need to redownload, but now GameTree is gone. So I check on Origin, and I can't find the SIMS 3 base package anywhere... Is it available? I see I can get all the expansion packs, and I have a few of these on DVD, but not the base game.

I guess I will have to buy it again, but that's the game she wants back on her MacBook, and she is specifically not interested in SIMS 4.

@Bluebellflora  please and thank you in advance

Do you still have the serial code for the base game? If so have you tried redeeming it in Origin?
