S4S exported meshes not showing up in blender?

Hi,

I'm modeling some clothes and once I'm done modeling them, I go into S4S and export a mesh in a .blend file. I have both blender 2.78 and 2.70 installed on my computer. When I import the exported mesh from S4S into blender 2.78, nothing is there. Same with 2.70, but I get an error message this time. Im using the Wishes version of S4S. Maybe I need a different version? Any help would be appreciated.

Thanks!
