Added stuff from sims resources sharing thing and now it won’t launch

EDIT UPDATE: I figured it out I just went through and deleted everything in the actual sims 3 files that I downloaded the day that it wouldn’t start and it fixed it

so I was playing sim and then I finally figured out how to download other people sims and other things like that from the resources page the trading thing I loaded a couple into my game and I loaded it up it worked so then I was like a ok cool and downloaded a bunch of other sims and accessories ect so I finish with that and then I go to load into the sims 3 and it won’t launch properly like it will act like it’s going to load and gives me a black screen and I waited like a half hour to see if it would load but didn’t so my thought process was maybe I just overloaded the game with installed content from the gallery/exchange thing and I didn’t want to go through and delete every single thing by hand so I deleted the sims 3 thinking it would remove the stuff from my game i redownloaded it I tried to launch it again it didn’t work and all of the stuff I had picked out said it was still downloaded to my game so I tried to delete it from the launch area and I got a little black screen that shows when stuff is deleted but it kept saying sorry this app isn’t responding so I restart my computer thinking it’s just being slow but it still wouldn’t delete stuff when I reloaded into the launch screen just says unresponsive ansi still can’t get the actual game to load and still get a black screen that never loads 

if you took the time to read this I appreciate it ansi hope someone can help
