I'm sorry.
I own the game, but lost my install disc, so I downloaded the torrent for the game (I'm not even just saying that, I have discs 1 and 3 in front of me but can't find the others).
I had it running fine, and using the FF8 Launcher here,
http://forums.qhimm.com/index.php?topic=7248.0, I was running the game at hi res without any problems. I should've stopped there but the music in the PC version was always so bland to me, so I tried downloading the FF8 Configurator (Ficedula's Version 2.2). I think that is the point where it stopped working, and I was trying to use Samuel's DSL mod (it was on the same page as the configurator).
I'm running Windows on Bootcamp on my Macbook Pro, and this is the first time I've had a problem I don't know how to fix. I've tried uninstalling and reinstalling, but there is still no music. I've tried deleting the entire contents of the FFVIII folder (including the Configurator and all that), so I assume the problem lies deeper? Any help would really be helpful.
And like I said, I CAN use the first disc if I wanted to, but it doesn't seem to fix the problem either.
