Ah yes damn, the latest version of arranger.ly has a bug on line 112. 
[(= n 0) crashes when n is not a number)]
I had reorganized this portion of code but I did not see this error 
because it only impacts a very small number of functions (including 
export-instruments!).
Sorry about that.
I uploaded the new version (see link below). As only arranger.ly is 
concerned here is the direct link for this file.

I also very slightly modified your code so that it can adapt to 
arranger.ly
Everything should be fine now

Good reception.
