Store content says it's downloaded, but doesn't actually show in game
Having issues, and I'm completely new to downloading store content, so please bear with me as far as dumb questions go ☹️
So my boyfriend downloaded Sims 3 from Steam for my birthday awhile ago. I just had to recreate my account on my laptop, therefore deleting all of the game files I had previously saved on my old desktop account (didn't log in and save before, I just freely used the game and saved and didn't think about it when recreating this account on my laptop) and in doing so I made a new game and decided to purchase some store content while at it because ya'know, why not?
Anyway, I bought a hairstyle, two wedding dresses, the wedding cellar arch and the "woodsy wedding arch". It said it downloaded to my launcher. Cool.
I go into my launcher and download. It says it's ready to go and it's available in "build mode" (cellar arch) and the rest in either "create a sim" or "buy mode".
But when I go in game, NONE of the stuff appears. And when I exit the game it acts as if I never downloaded it in the first place, asking me to download again. Annnnd then it repeats what it did.
I'm frustrated because I bought these items and I want to use it and the game isn't giving me clear instructions on what to do with this predicament... Please help? ☹️
