Vray gi calculating issue

hi
i am working on a scene with vray and i am about to render it .

i am using irradiance map as primary and light cache as second

i set the irradiance map to save all calculation to file using incremental add to current map and the light cache set to fly- through .

in global settings checked - don't render final image.

in the common settings is set it to calculate every 5th frame .

pushed the render batten .

now the problem - it seams that when i set the out path for the gi it creates 2 files- each one for the primary and for the secondary but the issue is that when it calculates the size of the file remains the same size - few megabytes .

when i am trying to render with that "calculated" maps the renders pops out without gi at all .

first i send it to be calculated over the servers and that was the result so then i tried to calculate it locally on one machine and the result was the same .

what i am doing wrong .

help !!!

Thanks

Dan
