Fly Wiz DR Light map error

Dear Subburb team,

I have two problems with the Fly Wiz using DR.

1.)
I try to use the good looking fly wiz option in SR with DR. But although I saved the path for the LC/RR map the Vray Log is telling me that it can`t find the "light map": "Error Loading light map from file". I thought I may have to check "Share LC" in the expert mode, but I still get the mentioned message.
The result is, even the process is going on (LC+IR calculation) that the final render looks pretty bad and has spots from missing light informations......
2.)
Several times when I was starting the calculating process (LC+IR) and they finished, during final rendering the render hosts dropped off, so only the main render mashine works on his own, so that the animation takes several hours.

I would be glad to hear any solutions for this problems!

Best regards
