Alright so here's the deal.. I too had the same problem with the corrupt data (US btw) and just couldn't get it to work. Well, in order for it to work here's what you have to do..
1. Go to multiplayer then to split screen
2. Join using controller 1 and create a profile EXACTLY as follows "TERABYTES2"
3. Save the profile if you didn't already then create another new one and name it "TERABYTES3" and save
4. Now quit the game and go into saved data utility and copy both those profiles to your usb flash drive.
5. Download the profile "TERABYTES2" from the provided link in the tutorial and move and replace everything in the profile on your usb drive.
6. Download the MPDATA file from the provided link and drop it in the profile "TERABYTES3" on your usb drive.
7. Now copy those files and overwrite onto your ps3.
8. Then just follow the tutorial from there.
The problem was that everytime you change the name of the folder, for example originally it was "terabytes2" and you changed it to "terabytes2 copy".. it will show up as corrupted because the name is encrypted or saved somewhere in the profile save, meaning you have to create a profile (unless you want to be a 1337 h4x0r and hex edit) with a new name for it to not be corrupted. That should clear up a lot of issues, if not just post your problem in this thread. Don't go making 4 other threads about the problem, patience is key
