When you open the Trainer, there stands "S4 League not found" on the bottom of it, right?
So what you can do:
Open the Patcher->press start and while game is loading, "S4 League not found" will change to
"Ready to Hack /Sp Hack:OFF etc.."
If this appears, push the "Sp Hack ON" button quickly and close the Trainer.Now you will have unlimited sp
Or you hack the Resources ;D
