Error When Importing Mesh

Hello! I am very new to 3d meshing and blender, so I'm sure the error is mine here. I'm attempting to import a mesh into sfs, but I keep getting this error:

I am using Blender 2.76. I've been able to import meshes before in this project, it's just when I made some edits that this error message started. I'd appreciate any insight, thank you!
