Well, I had bought this game yesterday, so it crashed down for 2 times. One time was, when I tried to set a new skill (exactly: when I clicked "Apply").
I had started the game again, loaded a saved game, and I set a skill successfully.
After 5 minutes I had decided to start a new game, of course I clicked "New game". After a moment, a process of loading was approaching to the end... and the game crashed again.
Sometimes when I try to save a game, the game gives its own message (!!!) that an error occurred during saving to the hard drive.
I have no problems with my hard drive. It is new and I've checked its surface (just to be sure)... No errors.
