Nothing showing up when trying to start game.

Hi, I have just installed all expansions and cracks. I followed the instructions exactly, or so I thought. I click on the Sims 3 launcher and it starts up the game. However, when I get to the spot where I am to select my world/create new game, there is absolutely nothing showing up. No neighborhoods, it won't let me login, won't let me create new game. Nothing. What have I done wrong? I used this on my old computer and everything worked perfectly. I bought the Sims 4 and didn't like it, so used this to get Sims 3 again and it's not working  Please help! Thanks so much!

And now when I try to play the game, it tells me to insert the back to the future disc.
