Ok, here is a step by step on how to make the saves work. It's quite simple.
1) Copy your save and your profile from your ps3 to your computer and save them in a folder called MY SAVE. the reason for this is so you will have your original save to go back to once you are finished using the saves. Just insert it back onto the ps3 when you are done with the files.
2) Download the saves from the site and save them in a folder called GTA Saves
3) Open Brute Force and load your save. NOT THE PROFILE!
Ignore this and the next step if you are using a US game! If playing a US Game, go to point 5
4) Copy your title ID if using a EU game into note pad.
5) Now load up the save you want to use in game. If this save is US and you are using EU, copy and paste your title ID into the US title ID section. You will now have two versions of the save, 1 US and the other EU.
6) Now Now click on Update Account ID and select copy PARAMS (First option)
7) Then click On Verify PFD

Then Rebuild and Rebuild Full
9) Delete all GTA Files from your PS3, except the one which lets you redo missions.
10) Now go to the save folder which you are using, eg Close Shave. Inside this folder you should have two versions of the save, one BLUS and one BLES is using an EU save.
11) Copy this new save onto a memory stick and put it into your ps3. Copy the file from the stick onto the ps3 and load the game.
12). Now follow the instructions in the READ ME! attached to the save and the trophy will pop.
Hope this helps those who are having trouble.
