Blender v2.77 Traceback (most recent call first) error

I’m trying to import an FBX with the error mentioned in the title. I’ve seen the thread on replacing code in, but that doesn’t work for me.

Here’s the error, if it’s of any use:

I’m going to guess, you haven’t exported out FBX properly because it mentions dimension of 0.
Perhaps you can convert the FBX to an obj file and see if this changes anything. I’m still not sure why you would do anything to the game engine runtime code? this is an import error not a BGE error from what I can tell.
