Cannot find repair button for Sims 4

I don´t have any mods and am going through the same problem! I tried to search for the file they say it´s corrupted, the file doesn´t exists.

@tayecuianachina  If you've installed Sims 4 through the EA App, the Repair option should be under Manage when you're viewing the main Sims 4 page.  If you've installed through Steam, you'll need to repair through Steam; the option is called "Verify integrity of the local files" or similar.

Since nothing worked, I had to re-install everything, EA app and The Sims base with the 64 add-ons yesterday and went to bed. Now that everything has been downloaded again, the EA app won´t start. The page stays black like this. Doesn´t matter how many times you reboot everything, it is just broken everywhere. 

This happens now. 

@tayecuianachina  Please uninstall the EA App with Revo Uninstaller (the free version is fine).  Use Hunter Mode, which is the most comprehensive search.  Restart your computer before reinstalling the App.
