Melphias: Azure and Crimson Verge

at the first 'subquest' when reiko invites the player to the game start, entering a building to progress makes it crash attempting to load drakima.png, even though the game doesn't use .png files at the /img folder, is there any way to fix that? (alr tried putting a fake drakima.png and .rpgmvp but didn't work)
