When I fought Naga for the first time, I lost and then went over all the events again... in the dream scene of Jun's brother and father, I clicked fast because I have read the conversation already, but Jun's father turned left and the game froze. But I manage to overcome this little glitch.
Now, after I left Kurosawa Forest with the cure for Jun's poisoning, I gave him the flower to heal him and the party went out of the room... I went to the table to talk, the characters talked a little and then the room door opened and the game froze.
EDIT: Downloaded the game again and worked, but I couldn't go to the roofs of Azima Checkpoint and when I talked to the guy who let me in, he said the exact same thing when I first entered the place, also I could pass throught Lady Asuka

And where do I have to go after I get Lady Asuka hawk-message?
And this happened:
I managed to evade this by pasting a music with the same name that I've found in The New Queen music folder.
My HP and MP run low everytime and there is no shop for buying medicines in this continent, what I can do?
