Blender not exporting nifs correctly

[AuroraLily]

I'm having a little problem with blender.

 

I've played about with blender before and not had any problems exporting so i'm not sure what's happened this time,

 

I imported a nif into blender, flipped it and then tried to export it and this is the result: inital nif compared to new nif

The object looks fine in blender.

 

I installed blender as per the download and instructions on the nexus.

 

Any help would be great.g.

 

EDIT: Problem solved after much googling - had to flip normals in edit mode after mirroring
