Sims 3 Crashes while traveling

I have downloaded all of the expansion and stuff packs and they had always worked perfectly, thank you guys. Then I started downloading mods and no problem arose, but later I started having problems while traveling, the game crashed to the desktop showing a message of "The sims 3 has stopped working". I tried to check if the mods were conflicting, so I took the folder out and entered the game again.

I tried to travel and the game never crashed, but it kept loading endlessly! I kept waiting for more than two hours for the game to finish loading, but it never ended so I resetted my computed manually. And I never figured out if the mods were causing trouble. What can I do now? I can play the game with the mods folder in, but if I take it out it's also unplayable and I will never know what is causing trouble

I will take a look to it

Edit: I tried the mod, and the game still crashes. I didn't remove the others mod although, but I don't know if it's the best to do this because maybe the game wil never finish loading.

//EDIT

I tried a different thing. I took out "The sims 3" folder to the desktop
and tried a new game. Travelling was possible. In that new game I put
the "Mods" folder in, and I still could travel. After that, I put my
"Saves" folder and it still worked.

Then I tried putting the
"Downloads" folder and first, I had a lot of trouble trying to install
them all, because at first it said that they all had success, except a
few. I teid reinstalling the missing ones and it succeeded, but then the
launcher showed that there was still some content that remained
unistalled. I re-installed them but I got a message that said that they
were already installed. So I have some content that shows as unistalled
but is installed.

Then I entered the game and couldn't travel, so
I'm guessing it's because of CC. I heard there is an easy way to manage
CC called CC Magic, but I don't really know how to use it. How can I
spot the file (or files) that are causing trouble?

PS: While I
was trying to get the game started, I got a few messages sayiing that a
serious error had occurred and I had to restart the apliccation. What
does this mean? I loaded the game with another save file.
