Exporting SKI error

Soooooo i was redesigning some armor for a private server and got around the beginning just fine. I was able to extract the files and edit them, but now I want to return them back into their SKI format (currently they are in 3DS format for editing) Blender allows me to reformat this easily, but for some reason i get this error:

AttributeError: 'Blender Material' object has no attribute ' enabledTextures'

Hopefully this is just some noob problem I am having since I'm pretty new to using blender, but can anyone tell me how to fix this?

Open old one and new one .ski file with any hex editor, that can open file with it structure (sorry 4 my bad english). And than just compare whats wrong.
