Can't play any musics...

[MIDNIGHt]

I downloaded the Latest Release (1.4.5) and extracted to C:\HLDJ, I put some .wav songs in there (C:\HLDJ\Audio), I made all those things about the directories binds and stuff... then I went playing Zombie Master,
but it didnt work instead of playing musics, it just started mah micro... and instead of musics players could hear mah song...
Then Iwent to the site and noticed on the "Current Build 1.4.8" so i downloaded it... renamed it to "hldj.exe" and replaced it for the 1.4.5
Then i went playing and it still had the same error so i dont what to do...
Can some one help me??
I do "la" then the number of the music (I have 37 musics in the folder) and press the bind key... (also tried "Playaudio") and it doesnt work...
