Grandia_II_Echelon troubles in playing

I am playing Grandia II, after about 1h00-1h15 when having a big battle with a winged darkness girl at the Village, after she destroyed the church, the fight begins, I normally lost (coze this is scripted in the scenario) then nothing happens, I can turn around my guy, wich is having a skull icon over him, then nothing at all, I can zoom, de-zoom, rotate and nothing goes beyond, like if something should happen but doesn't.
Anyone Help ?
Using an European DC with the RGB Scart cable sold with the console.
And by the way, did, U notice that, the second CD of Echelon Grandia II release, is booting black screen on a DC using a RGB Scart cable ?
