I'm not sure whether you're still having the problem but I not long ago had the problem too, I do everything that everyone stated above but nothing even played for 5 minutes (probably longer) but I think I might of found a way you can find it, Not sure whether it'll work but...
Click on This PC, then Click on your C Drive, which'll look like this -- Acer ( C : ) (Without spaces) -- If you've clicked on it, then you'll see a bunch of folders, Some with program files, etc.. Click on the folder that says 'Users' then once you've done that, Click on the one folder that has your PC's name on it, Like what you've named your PC, For example mine's -- Shyanne -- As that's my name, I know original, but once you've done that then you'll see all the same folders you have at the side but for some strange reason are completely different, click on documents after the PC's named folder, once you've also done that you'll be directed to some more folders, Click on Electronic Arts then Sims 4 then Mods.
Hopefully this helped I do really suck at explaining stuff, I also tend to babble, If you understand anything from above then awesome.
If there's nothing there still then I have no absolute clue, I do hope you get it solved quick though as I know it's horrible specially when you'd like to play the game.
