shining force cd on gens

In shining force cd, one of my all time favorites, the second book freezes right after Warderer sends his henchman away. Any body who knows why this is happening please tell me. btw im using my backup version.
Gens 1.7 emulates the game perfectly...If you are using the iso/mp3 combo, you need to follow the naming instructions for the mp3's per the read me in the gens folder...If the burnt copy is freezing too, redl it.
