Yami no Koe IIForum

My computer doesnt recognize that the second disk is loaded into the drive and can only seem to install the first. All of my settings are in japanese and im running as admin etc, i just cant get it to recognize the second disc is inserted. I have noticed that its called yam2_2 whereas the first disc is called yami1_2, do i just need to change the title somehow? any help is appreciated, id rather not settle for playing the game without voices
