Hi everybody,
I wonder if you solved this problem, because I've the same problem (button load and continue are grey) and I tried Mr E.S's solution but it didn't work. I tried uninstalling and reinstalling the game but it didn't work either. I tried starting new games and save, but everytime the save is corrupted (ZIP FILE WAS CORRUPT in the outpout_log.txt). I don't know what to do, so do you have any other solutions to deal with this problem ?
