I'll try to reinstall it to just C: or D: or something like that, since I did install it to C:\Program Files. If that doesn't work, I'll post the values for the ambientmusic.2da.
I think reinstalling had no effect, but I managed to solve my problem. I had to enter EVERY field manually, not just the (Row Label), (Description), and (Source). Apparently, it doesn't save if I don't enter "****" into the "stinger1", "stinger2", and "stinger3" fields. It seems Kotor Tool, for some reason, doesn't automatically enter the **** into the empty fields. Oh well.
Thanks a lot for the help though.
