Game crashes trying to make neighbourhood

[Snuffleupagus]

every time I try to make a new neighbourhood, my game crashes (it reaches the second bar then dies). No pop up messages about errors. Just closes.
I tryed changing my downloads folder so it was empty because I thought it might be having problems with all the downloads, but it didn't do anything.

Anyone have any ideas?
Much thanks

UPDATE
Okay, I ran my Hack Conflict. Turns out some files that I, am sure, deleted popped up again in the folder. My Inteenimator and inteen flavor packs have a conflict.

InTeen and the Flavor Packs are suppose to conflict.

ancienthighway, that's good. I thought perhaps I was doing something wrong, though I never had the two of them together.
Well I tryed making a new neighbourhood again and it still crashed. I don't know what to do! This hasn't happened before.
I have all EP's up to pets.
I did try the game update and patches from the Sims2 website, but I don't think it did something bad to it. Luckily I made a copy of my game on disc!
But now it won't let me make a new neighbourhood! And I'm repeating myself!
I'll try something else.
Has this happened to anyone else?

This is happening to me too! Except it happens when I try to create a family.

Snuffleupagus - Were you able to create neighborhoods since getting Pets, or is this the first time you've tried?  Try taking out the Downloads AND SavedSims folder.  If you have a bad mesh, it could be in either folder and crash your game.  If the game works without both folders, take a look at the thread I posted for agressivehobo.

agressivehobo - It sounds to me like you have a bad mesh.  Take a look at this thread and see if following it helps.

ancienthighway - I'm not sure about the Pets. I think this is the first time i've tried making one with Pets. I never thought to try it out when I installed it. I'll try what you recommended.

Okay, I tried it and it still crashes. I'm just going to package the family's I've changed and reinstall the game I saved.
Thanks for your help, ancienthighway.
