Yesterday I downloaded the game from a megaupload link. I downloaded the game not in pieces, but all of it.
When I started playing I noticed that sometimes appeared a little window saying 'File[BGM_02.wav] could not be opened'.
Of course the number of the wav file changes, depending on the scenes I'm playing at. I can hear the voices of the characters and the other sounds, but not the 'soundtrack'. What can I do to solve this problem?
