MK9 Skeletalmesh tool - Reptile error

[judgmentfist]

Hey everyone. I really need some help. I've used aman's skeletalmesh tools for quite some time now and have the method pretty well figured out (23 characters done) but finally am getting to Reptile and his main mesh file won't import correctly. This is the error I get...

Traceback (most recent call last):
File "/Users/[myusername]/Library/Application Support/Blender/2.79/scripts/addons/io_MK9_mod_tool_v0_2.py", line 948, in execute
getInputFilenameMod(self, self.filepath)
File "/Users/[myusername]/Library/Application Support/Blender/2.79/scripts/addons/io_MK9_mod_tool_v0_2.py", line 931, in getInputFilenameMod

bInfo.Parent = ReadShort(f)
IndexError: list index out of range

location: <unknown location>:-1

I can't export to the Reptile skeletalmesh file, either. This is a pretty huge problem Any help would be appreciated. How do I get this to work?
I've attached the skeletalmesh files for both Reptile and Reptile_B (which DOES work).
