So after a long while of not playing the game, I recently decided to try and get back into playing. when I Tried to load an world I got an error. So I decided to delete the old sims 3 folder and relaunch the game, which fixed the problem, and then I had access to all my store content again. There was something wrong in the file, and I know I've tried that before, but this time it decided to work. However, I think my main issue was onedrive. Every time I'd fix it onedrive would revert it back. So now I've disconnected onedrive and that seems to work XD
