H E L P ! ! ! Sims 4: Households won't load, it takes me back to the main screen.

Hello, 

I have downloaded the game before from this particular website and it worked perfectly, but after a few months, my laptop had some viruses and I had it fixed, so everything was deleted.
I got my laptop back and I downloaded the Base game and the Get to Work expansion. The base game worked fine until I moved the Get to Work files and followed the exact same steps as the instructions.
The game works fine unless I select a random household and press the Play button, it buffers for a while and then gets back to the main menu with an empty error box and an OK. (https://i.servimg.com/u/f62/19/81/61/41/simsno10.jpg) 
So, obviously I can not play because the Live Mode never loads as it should.
This has never happened to me again, I hope it can somehow get fixed.
I checked other possible solutions, nothing seemed to be close to my case.

Note: No mods in the game, absolutely nothing.
I downloaded everything from the beginning and I followed the instructions correctly.
Note #2: Even though I installed the Get to Work expansion, it doesn't seem to have been correctly installed, because no updates or anything came up on the screen as usual, so I guess there is something wrong with the installation.
Note #3: I tried deleting the Get to Work files and the base game seems to work fine.
(But the thing is, I have to install so many other expansion packs and I'm still stuck with this Get to Work error.  )

If anyone else had the same issue, please comment below.

Thank you in advance.
