I can't change to a new character's route! I finishes Neil's story and wanted to move on, but every time I try to choose somebody else and come back out of the menu it is stuck on Neil chapter 28. Help??

Hi, I've loved this game so far but I'm having a bit of trouble with the save.  I've had to restart twice now and maybe it's my fault for the first time?  The first time when it would ask me if I wanted to save after a chapter I would click yes and I thought that would be fine but when I came back the next day to play it, it didn't give me the option to load to my last save so I just restarted which kinda sucked.  So I instead tried to save through the setting button and closed out the game to see if that would work but when I reopened it, it just showed the screen where you first start and asked me if I've already played the beta version and I have to go through everything again.  Thank you in advanced for your help! 

Hi! I'm super excited for this game but ii kinda experienced the bug on the scene where you fall on Neil (in boutique) where he tripped.  i restarted the game 4 times but it would be the same. i'm using windows 8.1 btw . Hope you can figure it this out because i Really wants to play this game T^T
