Hi,
After i finished writing my config i launched the game to see if my musics are playing correctly, first i had some crashes due to the victory trigger but it's possibly due to a mistake from me.
I removed the victory music and then i could join a world.
I wanted to know what music was playing when i spawned so i used a recorder, wich had no texture by the way.
I used a blank cd and when it popped out of the recorder the game crashed.

The crash log:

It looks like the mod always assumes you have menu songs and crashes when you do not. Ill push a fix for this later

This has been fixed in 5.1
