Valkyre profile(spelled wrong?)

I have a few problems with this game!!!
1.the game voices are always cut out at the end.
2.sometimes the voices "forget to get played" and then the game freezes.
the music still goes on,but no button exept the "messege history" button responds.
[EDIT]
3.in the Cave of Thackus,when I reach the pentogram,nothing happens!
