overwriting

[tread]

Okay, this should be an easy one for most. Maybe I've just been sitting here too long, but I cannot figure out how to overwrite an existing disc.
The problem: The disc's song list is one song off throughout the disc making every song listing WRONG in the book.
SO, I went back and adjusted the list accordingly, amd when trying to upload into the system, I get the error message Book ID already exists.
What to do???????
How do I re insert a disc for copying to the harddrive correctly?
