Installing additional expansion packs?[SOLVED]

Hello. I am unable to use the search function on your website for some reason, so I apologise if this is already an answered question. (I am unable to do many things, oddly enough-- I can't even visit official game websites..)
Anyhow..
I currently have The Sims 3, Ambitions, Fast Lane Stuff, Generations, High-End Loft Stuff, Late Night, Outdoor Living Stuff, Town Life Stuff, World Adventures and every store update you have on your media fire page. (Props to you guys for being so super awesome.)
I have already played the game and it works PERFECTLY, thanks for that in the first place.
But, I was wondering if I could still install additional expansion packs/addons (Diesel Stuff, Showtime, Master Suite Stuff, Pets, Katy Perry's stuff) without messing up my game? I ask before I attempt because it was a lot of work to install all this stuff and I don't wanna have to uninstall and reinstall everything again XD
I'd assume that I just install it like I did the other ones, and apply the cracks in the same manner...

TL;DR Can I install more expansion packs even if I have other ones and I've already played?

Yes you can install more EPs and SPs without ruining your save game. Simply follow the steps HERE

Cool. Thanks so much for the instant response and thanks for linking me to the appropriate page.

Hello,

Lol, hard to miss(?), I guess.
