Game isnt loading.

Hey, so. Everything was alright, i played with cc, without any problems. Today its said i had some corrupted files, so i deleted them everywhere that i could, mods folder, disc, ect. But then my game completely stopped working. Anytime i try to launch the sims, it goes straight to ea games launcher, and when i try to launch  it through the play button there, it reopens the launcher. Its not letting me enter the sims. I have already tried to fix it by following youtube tutorials but to no avail. Any ideas why this might be happening? Please inform me, thanks.
