By no means am I a ripping expert (never ripped a game in my life!), however:
If you still want to re-rip the game, make sure that you follow the rip info exactly. For a 4 CD rip, you will need to extract the game, apply the rip bat file once, then extract the game again rip 2, etc.
Make sure you have the right kit also, check out
