I've tried using multiscatter many times . But, whenever I use this plugin , I get this error ---
" UNHANDLED EXCEPTION: Preparing instances Last marker is at .\src\vrayrenderer.cpp, line 2287: Preparing camera sampler".
This happens all of the time . I just can't seem to get this plugin working .I've also tried installing/uninstalling many times. Please see the below image --

My system and software specs are-
3ds Max 2011 x64
vray 1.5 SP4
i7 860 2.8 Ghz
8 GB Ram DDR 3
What's even strange is that ,it's working perfectly on my old Xeon machine . Please help ..I am really looking forward to try this plugin.Any help would be appreciated .
Thanks.
