Odd DTS Exporter Problem

I am currently writing a DTS exporter for my favourite modelling program, based upon "ms2dts" from the torque cvs.

However, i am having lots of problems when i try and apply textures to the model i am exporting, which i did not run into before (and i do not use cvs/subversion so i cannot rollback the changes i made to the code to see what i broke :( )

The Model (Simple Square) should look like, and used to look like :

But now it ends up looking like :

I'm pretty sure that the texture co-ordinates themselves are being written correctly, aswell as the vertexes, meshes, etc.
I really can't figure out what the problem is.

Does anyone have any idea what i am doing wrong? Have i written some incorrect flags somewhere?

I have 1 material, and it has these flags :
"SWrap", "TWrap", "NeverEnvMap", "NoMipMap"

The mesh has no flags (0)


I am writing a mesh "Plane", these vertexes :

-10.0000019073 10.0 0.0
  -10.0000019073 -10.0 0.0
  10.0 -10.0 0.0  
  10.0000038147 10.0000019073 0.0

These corresponding Tex Coords :

0.0 0.0
  0.0 1.0
  1.0 1.0
  1.0 0.0

All vertexes have this normal :

0.0 0.0 1.0

And these triangles (Vertex Numbers) :

1 2 3
  0 1 3

The Exporter reports it has written :
(Vertex followed by tex coord)

Thanks for any help.
