There is an update since like a year ago that adressd several bugs and controlling issues.
I would suggest checking and downloading the updates before attempting to replay the game. Also try out first to install the game in another computer just to check, maybe your computer is missing something in particular that is causing the problem.
Sometimes save files fail and in a very very small percentage of users. Has happened to me a couple of times with other games. My suggestion is to start a new file and reach the point again. I know this sucks but you might take more time trying to recover your file instead of just replaying the game.
Hope you can enjoy the game!
Also this brought me memories of the time I didn't have a Gamecube memory card and every day I replayed my games until the point I was to try to beat the games or go as far as I could. Imagine playing Wind Waker without a memory card and being hooked on the story
those were the struggling times!
