Can anyone help me resign a save file?

I'm just trying to beat White Knight Chronicles 2 and don't feel like spending any more hours leveling up on it as I have so many other games to play. I'm even at the final boss, just having tons of trouble taking him out at my current low level. This is the only game I plan on doing this with, so I'd love some help, as I've wasted so much time trying to resign it myself only to fail. It comes out not working every time, and I'd rather not spend money on easy programs since this is the only game I plan on doing this sort of thing with. The gameplay has just gotten so stale, and it'd take me hours that I don't want to spend leveling up.

My Data:

Modded Save:

I'm not sure on whether or not it is same region. I'm in North America, not sure where the modded save is from.

Much appreciated.
