Need help please: Expansions won't work after reinstallation.

Hello,  :newfag:  I've downloaded a bunch expansions and they are giving me a hard time. ( Pets, Seasons, Supernatural, Master Suit Stuff, Island Paradise)

I got them all to work a few months ago. But after an uninstallation cause of a in-game problem, I try to get them back to work, but everything I do fails.
So I have these 2 computers, one where my gf plays the Sims 3 on all the time, that one runs Win XP, my laptop runs Win 7.
I had to do a reinstallation. So I have the original Sims 3, Ambitions and World Adventures.
Those work just fine, it's after I installate a none-original version the problems occurred.

On win XP, after pushing the PLAY-button I get the error 'The sims 3 has encounteres a problem and needs to close.'
I did follow all the steps from this Youtube guide (The Sims 3 "Error during Startup" fix by *Games4theworld*).
Unfortunately win XP doesn't have a Wow6432 Node. So I coulden't fix it.

So after that I tried to install it again on my win 7 laptop. Same story, original ones work fine. The other expansions don't.
When I push the PLAY-button, nothing happens, the Sims 3 starter just closes and the game doesn't even try to run.

I tried a lot of things already, also installed the All expansion pack... fix, diden't help either.   
Searched the forum for a solution, but nothing so far worked.
Sorry for my bad English.

Is your game up to date?
And did you apply the latest Ultimate Fix?

My Sims 3 and the first 2 expansions I have installed are legal, up to date and working.

It's when I try to install one of the illegal expansions that it won't work.
I follow all the steps in the guide and I'm kind of familiar with installing torrented games + I did it before and had no problems what so ever back then.

It's after I copie and replace the TS3W and TSLHost.dll files in the Sims 3 root folder that the problems start.
The game says it's up to date, so when I launch, the launcher closes and I get the following message:

"In Sims 3 has encountered a problem and needs to close. Sorry for the Inconvenience."

I can only click Error Detection, Send Repport and Don't Send.

PS: This person had the same problem on the forum:

But there is no solution either and yes my graphics card can handle the game for sure.
