hm, no one?

hi,
this is probably my first post on this forum, but i have always used the great info u guys share here, and i am thankful for that. the reason for not participating is mostly that i think i don't have any useful information to share, for u guys are pretty much more skilled than me. ( plus my english skills are pretty poor, as u see in this post )
so my problem is, when I'm going to use one of Irradiance map's mods as "from file", it just doesn't render properly and shows sample size as 0. I've tested this method on 3dmax and it was quite useful to save samples and made rendering multiple scenes quite faster, but in vfsu, when i choose any option beside single frame, it doesn't even show in the list! it just turns empty! and in the rendering produced shadows will be too dark.
i use the latest VfSU , 1.49.01
and i use win 7 64 bit.
and SU 8
any advice there?

oh and i believe the problem IS with my windows being 64 bit. i tested this on another system with 32 bit OS and it works just fine.
