Hexyz Force

[Elesiel]

I get several problems
1. I can't load saved game
I get

-- Load failed
The data has been corrupted ---

every time no matter how and where I save or if I even get save file from the internet


2. When I try to enter Tower of Judgment
I get stuck on the black screen
   

(I'm total noob at this so if you could answer in simple words and pointers)
