Just change "convex" to "ccw" in your models and they will load. This  
is a syntax problem with OpenVRML 0.14.3 I believe.

Hi,

I'm having some trouble when I load into ARToolKit
VRML objects that contains the Nodes: Text and
IndexLineSet. The IndexLineSet Node appears in black
and white, and the Text Node simply doesn't appear. Is
this ok? I'm using ARToolKit 2.70.1 with OpenVRML
0.14.3, Windows.

 Your Version of OpenVrml doesent make use of the VRML Text Node.

 Here follows some code  which functions in my artoolkit version:
 convex FALSE (or) TRUE    ->  artolkit will not load an Object with
 the field convex.
