problem installing the fix in the sims 3. [SOLVED]

First topic message reminder :

hi, 
I've followed all the steps but my game still doesn't work :/ . once the charging part is done, it tells me to create a new town (I lost my towns ...  ) and there's nothing I can do . Plus all my game is up to date (as it was said in the tutorial). Can someone help me ? I'm lost right now.

PS : I applied the fix as it was said in the tutorial . I ALSO FOLLOWED  the instructions inside the Ultimate fix .pdf. But I saw in another post that it was not needed to follow these instructions. so what do I do to step back and get rid of what I did wrong.

I tried that https://games4theworld.forumotion.com/t15765-how-to-recover-saves but it still doesn't work and the menu box is totally empty. 
//EDIT 
I think I used the wrong part of the ultimate fix, which I pasted in the different expansions' files. How can I get back the original files? :/

Ok, great! Thanks a bunch for your time
