Load Error Code 800/801

Yesterday's update broke my game, I can't even play my game now.  I play with mods in my game, I know the whole thing what to do before updating with mods and after. I removed all my mods from my folder and deleted the old MC expection. and update my mods after the update. without the mod, I did the test run without any mods, everything looked fine then I exited the game without saving. I add back my mods in the game when I want to move my sims to a new house. I get a warning that says "  can't load needed to relaunch the game". so I did but when I did the same thing I got the same warning so I removed my mods and repaired them without my mods. I checked the second time it was giving the same warning. I didn't know what to do I repaired my game and even restarted my computer and nothing is working. My game was fine before the update now I can't even play the game.
