I tried with different versions of Poseray all were like yours.
Tried Lightwave but it was problematic too.
Same with Blender and Netfabb.
Only Mootools 3D Browser could open it without any problem but it is only the free version and i cannot export it for you.
Maybe other users here with the same or other programs like 3DSMax etc. might help you.
Then i just tried this online converter
http://www.greentoken.de/onlineconv/I exported as OBJ and it looked OK in Poseray.
Not sure about the textures but try it, it took only 5 minutes.
