Doesn't work in Left 4 Dead

[Bud]

I'm getting the same problem as this dude:
http://www.hldj.org/forums/viewtopic.ph ... p=979#p979
I load the song, I hit play, and it pops up with that error message
I'm using the 1.5.0 Beta and all the song files are in the right format, frequency, etc
Works fine up until I hit play
Any help?

Your game crashed, likely because the audio file was converted improperly. Alternatively this may occur if you have a dual-core AMD. In either case, there are links in the stick on guides for both situations; here's the conversion guide:
