It took a few hours but I sorted this out myself, I can't say for sure what I did as most of it was guess work but I reinstalled the kami_001, kami_002 and kami_200 without deleting or replacing the old files and it's fixed it.
When I first booted up the game for the first time I clicked the Extra Stories button instead of the new game one by mistake as it was on top of it and it took me to the option to choose between the two available stories or return to main menu. I clicked return and this time clicked new game and now I've finished one route I want to read the extra stories to go along side the new characters in NG+ plus, but now when I click Extra Stories on the main menu it doesn't come up with the option to choose which one I want to read and just starts prologue of the main game instead. I've searched around but no posts I've seen has anyone else mentioning this so any help?
