Cant create a new world or enter the old one

I have Sims4, and all of a sudden i couldnt normally play cus when I tried to create a world the program crashed. And then, when i tried to load the old one, i couldnt move on throught tutorial cuz i had no cash to buy a house for some reason ( i had house and fully customed world so). I tried to reinstall? but it didnt work. What should i do? Except waiting or reinstall cus, as i said, i already did it
