Can't download anything from The Exchange? (Sims 3)
When on The Exchange, I am attempting to download literally anything at all, lots, sims for example. Yet, nothing will download. I have used it previously so I know the way it works but nothing is working, when I attempt to download it asks me if it can launch the Sims 3 launcher (which I already have open), I agree, yet nothing goes to the download tab. I have make sure everything is up to date, my laptop and game, I've made sure all my internet settings are correct, that I can download pop ups for example and allows pop ups. But I still cannot do it? I don't know where to go from here..
(This is for Sims 3 on Mac, I have Sims 3, World Adventures, University life, Seasons, Pets, Late night, Ambitions, Generations, Showtime)
I have checked all over posts and answers yet none have worked for me. I can't stand playing the game without any extra clothing and lots etc from The Exchange, its to the point where I'm considering just buying Sims 4 but I love Sims 3 so would really love to figure out the issue.
