TypeError: execfile() argument 1 must be string, not None

Hello, I was trying to plot a quick locuszoom plot using some GWAS data and user-provided LD data (formatted per instructions) and when I run the command:

../locuszoom/bin/locuszoom --metal metal_file.txt --refgene GBA --ld my_ld.txt

I get the following errors:

Traceback (most recent call last):

File "/data/amccall2/work/NBB/LocusZoom/locuszoom/bin/../src/m2zfast.py", line 2102, in main

I keep getting this error too. Did you find a solution elsewhere?
