CAN'T OPEN/UPDATE SIMS 4! PLEASE HELP!

So, yesterday, I wanted to delete the lot51 plumbros mod because she kept complaining it smelt every second. I searched up "lot51" in the mods folder and deleted every single download that had that included in the name of the file (there were 3 files in total). It told me to update Sims 4 and I tried to but when I wanted to download it  after that it came up with this and didn't finish updating (i included the photo). I don't know what to do. PLEASE HELP ME!!!
