Unable to bake lightmaps (Blender Render)

[theonlyames]

I've been running into this issue and cannot for the life of me figure out what is causing it. Whenever I try to bake 'Lighting only' or 'Ambient Occlusion' lightmaps using the Blender Render mode, I get the following error:

**Traceback (most recent call last):
  File "C:\Users\Amy\AppData\Roaming\Blender Foundation\Blender\2.79\scripts\addons\io_thps_scene\bake.py", line 1003, in execute
    bake_thug_lightmaps(meshes, context)
  File "C:\Users\Amy\AppData\Roaming\Blender Foundation\Blender\2.79\scripts\addons\io_thps_scene\bake.py", line 621, in bake_thug_lightmaps
    test_mat = orig_mats[orig_index]
TypeError: 'NoneType' object is not subscriptable**

Here's the full console log:
