Texture "screwed" - Blender to UDK (using .ase Script)


this is what iam using:

Blender 2.69 with the ASCII Scene Export (.ase) version 2.5.1

If i import a blender-file in udk then one side of the cube (in this case) is “screwed” … here is a picture:

One side = screwed - the the other sides are looking good.

As a “noob” i am following this video from the creator of the .ase script:

For me my unwrap looks good and is not triangulated - after the export its triangulated but this is part of the script afaik.

Can someone help?
