The Sims 2 Doesnt Work On My Pc Anymore Why Wont My PC Game Sims 2 Nightlife Install? 10 Points Quick!?

Why wont my PC game sims 2 nightlife install? 10 points quick!? - the sims 2 doesnt work on my pc anymore

I had my computer games, Sims 2, Sims 2 University and Nightlife.
I uninstalled the night life after college, and left the original Sims 2 to her, to see if my computer run faster. No matter what I tried to install the nightlife and the university and college graduates work easy!
What happened? ?
The Thingo Autorun for night life does not seem to write like this D: \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ autostart.exe or what is in the "Run" and it does not work. It is as if the reader is not on there!
Please help by custom install or something else?

10 points! lol! Hurry up! I want my sims have a car with us!
