Guilty Gear X 2 problem

hi, guys!

I'm writing this because I'm having a problem a problem with GGX2:

I have the Kalisto release of the game, and it boots fine and plays most of the stages just fine.

But in some stages as soon as the fight starts, the cd stops spinning, and after the fight ends the screen just goes black :(

I've found that the cause of this is the in-game music, I'll explain:
acording to the Kalisto NFO file, to rip the DVD, they had to delete music from some stages and redirect some of the music from other stages.
In some stages there must be some kind of error, because when the game tries to play the corrspondent stage track, it can't and it just stops!

Even when I go to the sound options , when I try to play some of the tracks, the game just freezes and I have to reset the console :mad:

Is there anyway I can fix the problem?

If I have to lose ALL of the music tracks, I don't mind, I just wanna play!!!!

Many thanx in advance.

PS: Sorry if this seems a bit silly, but I'm a newbie at this.

PS2: I have burned some copies of the game at 1X and it still didn't work.

PS3: I've scanned the cd image with cdmage, and the program didn't report any errors.
