to all of you who can't open the next login sheet despite you already get 1 or 2 ending (be it normal or good end), you should contact customer service
I'm only on my 3rd route and I already can open platinum sheet
like I said before, they change the requirement so you only need to get 1 ending to open gold and 2 ending to open platinum
and there's no need to finish one login sheet to change to another ones
FYI, I just open my gold login sheet a few days ago, when I finish Asim and I can use platinum right away without even once finish gold
Indeed there's some kind of bug here concerning login sheet (looks like because they change the requirement)
Contact their CS and you'll get help to open your login sheet
[member=14781]Aquitaine[/member] : if you're already finish 2 route with 2 prince before, you should be able to open platinum by now
Oh, try to check your data...and look statement there which stated how much route you clear. If it's written 0, that means it doesn't count your ending before and that's why you can't open next login sheet
Good luck
