DR Vs Groundwizz

Hello, everybody!
I have a problem with groundwizz and Vray. I can not use the DR with groundwizz. The scene load on the other machines, but they can not make it (see photos). If I remove the trees it works!? You have an idea?
Thank’s


Groundwizz links :

Is that pluing installed on every DR machine?

and if the plugin relies on external resources (like tree meshes or whatever) do all the maschines see these assets ?

Regards,
Thorsten

Re,
Yes, no problem with the paths of textures (image3), and so on all the computers plug is installed and works very well (when I use the backburner).
Two new things! :
116 copies of a proxy = LC 37 minutes.(images 3)
350 copies with groudwizz = LC 6 seconds!

Other problems, my second computer calculation very slowly image. (Quad2_Q6600 = 4 clusters very low / malopixel_AMD_4800+= 2 clusters very fast = 95% of the image!!) (image 3)
Strange

Thank you for your help
