Grand Theft Auto IV

Perhaps a different region? NTSC and PAL saves are NOT compatible.

If the save was created from another profile then you will not be able to load the saved game. I don't know if there is a way around it though.

Unless the data got corrupted, it should work just fine. I copied the saved data on my USB Flash Drive....and my friend got a new PS3 because his Power Supply went on the Fritz and when I wanted to play GTA IV....the save file worked just fine. Since then, I've backed up all my game saves just in case it happens again.

This had happened to me...so I had to delete my profile...but make sure you back it up 1st

They probabily didnt copy it all or its from a different region

I have a question to your question, are you doing this to unlock all of the trophies? If so then you are wasting your time because the trophies are not retroactive.

Maybe you did it the wrong way so it got corrupted

Well, what i do to get a save and for it to work is...

WinRAR - you need WinRAR to extract files.

You download your save and save it on your Desktop, then you right-click on the little pile of books you should get, then click on extract here, you will get another file.

Save that to your Memory Stick/Drive, when you plug it into your ps3, go onto saved data utility, then select your Memory Stick/Drive, which should be at the top.

Copy your GTA IV file onto your ps3, thats how i got mine to work. If it still doesnt work, i'm sorry i can't help you.

Sorry for the length but i hoped it helped

Depending when you bought it, or what version it is, copied saves won't work. The creators of the PS3 don't want you to cheat on the game, so in one of the recent updates, the blocked saves created by people others than you.

If u want the save to work follow this
1.delete the updates and the install from the game data utility
2.copy the save to ps3
3.go into game click O on the update
4.the save should load
5.save it so it makes it your own save data

If it says something about not being able to load the file, you have to delete your game data (not the save), reinstall it into your PS3, and when it is finishes, you have to save that file in another slot, and delete the slot that it was in. Now, if you did it correctly, it should work.

And if that didn't work, you have to try formatting the USB stick to NTFS, FAT, or FAT32 (just google "Formatting USB Stick" and click on the first link).

saves only work for diferent version
if you have the USA version you must download the USA version if you have the europe version you must download the europe version
