The sims 4 won't open.

Can anyone help me? 

I have tried to open the sims 4 game in EA app but it doesn't open it, it says launching game and goes back to the EA page.                                                                                                                                                                      I may have accidentally deleted some files or folders that would be useful for the sims 4 for example, I can't find the electronic arts folder in my files.

Can this problem be solved or will I never be able to play the sims 4 again?
