BIG PRoblema

hi guys, first let me tell you what i did:
1.i download and installed a different base game sims 3, from another part, and i just updated so i can go on the other expansions from this site, i did that because i didn't notice this site before and when i try to install the base game from this site, the other one that i had was more updated so yes.
then i did everything is in the ultimate fix manual i only can install world adventures, high end loft stuff, and town life stuff (hardrive space) so i first installed world adventure, did not copy or paste any file, then i installed Hight end loft stuff, and finally tow life stuff, here i do copy the files on the "Supernatural & Diesel Stuff & Katy Perry Sweet Treats & Showtime & Master Suite Stuff & Pets & Town Life Stuff & Generations" and paste it on the base game folder, NOT the expansion, then i tried to updated...nothing happens says that is already updated, ant then i copy the crack inside "# Crack" folder. but when i run the game: first looks normal then when selection the neighborhood and that, you star to notice some bugs, and when i choose the regular neighborhood, it crashes....
HELP!!!!!!!

Okay so, You installed the base Sims 3 from a different party, uninstalled the base game and installed the base Sims 3 from here, got the following expansions from here, World Adventures, High End Loft Stuff, and Town life Stuff, then installed Ultimate Fix.

Have you rebooted your computer since you installed/applied the cracks?
Could help refresh some of the files needed since you did have the previous instillation of a Sims 3 from a different party.

You probably also didn't install any mods right?
Heard lots and lots of issues of mods doing weird/crashy stuff if have a incorrect version of one installed.
