madspads23 Are you seeing the "serious error" message? If so, please see the first post of this thread:
[Current Issue] Sims 3 "serious error" when loading save | EA Forums - 8322938
Please also remove all the files you've put in the game's program files, and repair the game in the EA App (Sims 3 > Manage > Repair). You shouldn't need to install any worlds that way, and doing so can break the content that comes with them.
Instead, let's fix the "serious error" when loading an already-present world like Sunset Valley and go from there. Once you can load SV, install one Store or custom world and see whether it loads.
