I Uninstalled The Sims 2 and it wont't instal

Hello, I downloaded the Sims 2 Double Deluxe and I played it for a month. Then all of a sudden it kept crashing and making me reboot. It said that my display or something like that was corrupted. So I uninstalled it to see if I could get rid of the problem. But when I tried to reinstall the game it wouldn't download. It won't put up the download screen at all. What should I do?
