I have seen this problem before, the geometry in the BB file is wrong, the 2 triangles used to define the rectangle on which the texture is applied are defined at the same position.
In this picture I have drawn the 2 triangles (1 red, 1 yellow) at the position they should be, in the BB file, they are both defined at the position and orientation of the yellow triangle, hence the texture problem...
I don't understand why they worked with previous version though...
Where did you get them from ?
It is possible to fix this issue using "Artlantis Implode Explode" application and a text editor.
If you want to do it, I can explain the steps to follow.
Let me know.
