Error with mod Musical Instruments

[FallenBR]

Hello friends

Receiving this error everytime I try to put a music spot anywhere in the map, from the mod Musical Instruments:

Root level exception in OnGUI(): System.ArgumentNullException: Argument cannot be null.

Verse.Log:Error(String, Boolean)
Verse.Root:OnGUI()

Mod is 1.0, but apparently is dead. Any suggestions for correcting this by myself?

Hi,
the mod itself is working.
It must be conflict with another mods you use.
You can try at first to move Musical Instruments at the end of the modlist and nearly at the beginning after the libaries.
When that don't help you need to find out what other mod cause the problem.
If you got hugslib too, enable Developer mode, then you got the icons on top, the right one is for quickstart. Shift-click to create fast a test colony.
Place a music spot maybe spawn some guitar's and check if the error pop up.

Then try to deactivate half of your mods and test again, until you can narrow down the mod.
Once you found the mod, you can ask these mod author if he know a solution.
