If you mean the white guy who transfers you to the library, I talked to him while in another form and he sent me there. Now he shows just 3 'grumble' characters and nothing else. Thing is, before closing the game last time, he did transfer me there. And I was like 'no, not the library again' (it's cool but I already did it once... It was enough) so I closed the game and said I'll play later. When I got back I'm in the main town and with all the doors closed.
This is also why I'd like to restart it but idk where the save file is...
Edit: these are all the rooms that I can access: http://imgur.com/a/mAd0c
