Please Help me

Hello
I am sujith, 3d visualizer
I am here with a vray rendering problem
i think someone can help me with this nutcracker I've been on for the past few day

my current project is an exterior view, so i am using multisactter plugin for trees & plants. When i render using this multyscatter vray shows an Unhandled Exception like
"
UNHANDLED EXCEPTION:Preparing instance
last marker is at. \src\vrayrenderer.cpp, line 2256: preparing camera sampler

but ,if i remove this multiscatter rendering is ok

My system is a new one bought last week
config- intel corei5 760 Processor ( quad core)
DP 55 WG Board
ATI 4670 Graph. card
4 GB DDR3 1333 mhz , i tried both win xp 64bit & win7 64bit

But an important think is that my old system( which is an AMD mechien) renders the above project with Multiscatter without any exception
old sys.config- AMD athlone X2 5600 Processor(dual core)
ASUSE M2NE Board
Nvidia QuadroFX 570 Grah.card
5GB DDR2 800 mhz

My new system renders 6 times faster than old one
So please give me a solution

The older has more RAM? I think that will also affect the rendering, specially if it's a massive scene. Try adding more RAM to your new system.

thanks bokkins
but sir i don't think it is a memory size problem because
i create a simple Sean with plane , multiscatter & sphere (scattering object)new system shows the same Exception
this Sean coasts only few KBs

does your 3ds max version is also 64 bit? have you tried to enable camera clipping in multiscatter settings?

thank u pedio84
yes i am using 3dsmax 2010 64bit
no i am not try to enable camera clipping , ti wii try it
another thing is that i replaced multiscatter with vrayscatter but shows same Exception

my wild guess..
video card?
i have an ATI card before and im having a lot of problems..
now im using nvidia and everything is going ok..
just my suggestion
