The sims 3 Pets wont finish loading

Hello, i'm a new registered user but been following the forums for a while. You guys do a great job.

My problem is:

I installed the game correctly, first the core game, then updated it.
Them installed ambitions, and updated it.
Then installed Late night and updated it. Then Generations and updated, then Pets.
Pets had no needs for updates once it was already in last versions.
Then i used a crack (lateste version) for the core game and bypassed the launcher to start game directly using a minidvd.

The game starts normally, loads normally the first screem. Then it gets to the part when we have to choose our first neigborhood (world, dunno) and no matter what world i choose, the game goes to the loading screen and gets stuck there forever. Around 98% of the loading bar. It does not show any error message, doesnt stops the songs, the tips keep changing and for all means it seems its still loading normally. But it never ever ends. Last time i left it there for almost 2 hours. and nothing.

Is this a know issue? Is there a way to fix it? ALready reinstalled the game 3 times, and once up to ambitions only. Only to ambitions it works normally. Didnt test others expansions separately.

What should i do?

I had this problem too, I just removed the entire mods folder and started slowly putting things back in to narrow it down to what the problem was.
