Sims 2 won't start up?

[PinkCherri]

Okay, when I try to start it up, It won't work. Like when you get to the screen where it says 'Sims 2' and when it has all of the loading things at the bottom, then it gets to 'Destablishing Orbital Payloads' it freezes everytime. I have the sims 2 clean pack installer thing, and I've already checked through it?

Delete groups.cache, accessories.cache, cigen.package, and the Thumbnail/*.thumbnail files.

I'm crashing when it says crash-proofing parties.  Will same advice work for me?
If So where do I find the groups.cache, accessories.cache, and Thumbnail/*.thumbnail files?  I came across the cigen.package file in my downloads.

Usually the cache files are one directory above your Downloads folder
under Vista it's like C:\Users\< YOUR ACCOUNT>\Documents\EA Games\The Sims 2
The Thumbnail directory you'll find  there too.
