@maddew123 Please click on the Sims 3 icon in your Origin game library, then select More > Expansion Packs, and scroll down to Late Night. You may have two or even three LN entries in the list; look for a Download button on each one, and if you see one, click it. If the pack says Installed already, please let me know.
I'm guessing you mean that the launcher's Expansions & Stuff tab doesn't list Late Night. Does it list High-End Loft Stuff? You get that pack with an EA Play subscription too; please install it and see whether it shows up.
I've downloaded it on my MacBook now, and it worked as soon as I logged into my account (by email) on the Sims 3 launcher. I then got prompted to download both Late Night and the stuff pack through Origin, which redirected me to the Sims 3 launcher. The only issue now, is I got no product code for the packs. Origin just said "no code key"(I think?) in place of it, so now I don't know what to do..
@maddew123 When you have an EA Play membership, the packs you get don't have product codes. This is not exactly a problem under normal circumstances—EA Play is supposed to be Windows-only, and the Origin/Windows version of the game doesn't require codes be provided during the install process.
If you only have EA Play and don't own Sims 3 separately, I'm surprised you could even download the base game. Are you only going to play on a Mac? If so, I don't think there's a way around this issue. Even an EA support rep would likely tell you that EA Play isn't supported in macOS, although you can still ask for the product codes. Maybe you'll get someone willing to help.
I'll be playing it on a Windows laptop! Just checking if I could fix it now since I only have the Mac available currently. But that makes sense, maybe I can try to log in through the Sims 3 launcher again when I have access to my Windows laptop. I own the Sims 3 separately! Just tried to get the packs through EA play.
I've supposedly managed to download Late Night and the stuff pack now, they're highlighted on the bottom bar of the Sims 3 launcher, but now I get a prompt about a "licensing issue" regarding the game whenever I try to press the play button (again, throught the Sims 3 launcher, not Origin). So now I can't start the game at all.
@maddew123 Please post a screenshot of the error. I don't recognize it, so it would be good to see its exact presentation.
