Missing BGM

[myomomi]

Hi Guys. I got some problem with BGM after I install some server client.
Before I install this client my BGM which is "Love forever" is the Morroc BGM of my old server.
but then the BGM is gone only for Morroc BGM the others still work fine.
I wonder if you guys could tell me that which "TRACK NUMBER" is this song suppost to be named.
I already have the bgm but it's named "Love forever" I think I have to change the file's name into number to make it work. or the only way to fix this is I have to reinstall the game  
Thanks you ,  in Advance
