Program won't start, throws a hash error

Here's the error log:
Traceback (most recent call last):
File "midiAuralizer.pyw", line 42, in
File "json_init_.py", line 293, in load
File "json_init_.py", line 346, in loads

Would be great if I could get this working because I don't have any way to render audio through a VST that doesn't involve a DAW that doesn't work.
