can't load CDG file from HD since upgrade to 3.3

[songpony]

It appears that I can no longer load CDG files from my hard drive since upgrading to 3.3 (at least not to an existing Book ID). The filename format I had previously been using was SC-2063-12-Song Title-Artist.cdg; I had the fields defined as Brand, DiskID, Track, Title, Artist (each separated by -). I would then select the Brand (Sound Choice), and the DiskID (SC-2063), type in the Book ID I'd already been using for this disk, Add Files, and all would be fine. Now when I do exactly this, it says that the Book ID is already in use - it also changes the brand to SC (which doesn't even exist) and the DiskID to 2063 (which also doesn't exist), then grays out those fields (if I were to change the BookID it would work fine, but why won't it let me use the existing BookID I've already used for this disk?). I've tried renaming the file to put Sound Choice at the beginning of it, but then it has a problem with a DiskID of "SC-2063" because of the dash in it. I've also tried defining the fields to start with DiskID, but then I have a couple of fields left over that seems to mess it up no matter what I put there. What file name do I need to give it in order for it to recognize an existing BookID? Also, I want the kma filenames to come out as SC-2063-12.kma (formatted like all of my other kma's). Any assistance would be greatly appreciated. Thanks!
