sims 4 not loading up

I haven't played in some time, and a few weeks ago tried logging in to play my game and it wouldn't load. so, I started trying everything to get it to load, but here is what's happening and what I have done. 

originally it wouldn't even load, we then updated the game and the computer completely. then it started to try to load but just flashed screens black and white then stopped. so, we then uninstalled the game and reinstalled the game. Once we did this it went to the spring sale, or ad page. Then it would freeze and not do anything. I have now, completely disabled all of my mods and cleared cache on EA app and the game itself. The same is not flashing black and white but once I get to the ad page it freezes and won't let me go any further. anyone have any ideas? - purchased through steam, my husbands to be exact but I use his on my laptop and he uses his on his PC- this has always worked as long as we don't play at the same time. I cannot get my own steam since I will lose all my packs.
