"memory could not be written" problem


When a try to run partdmesh or partnmesh for some files, I obtain the following message:

Instruction at "0x004038e8" referenced memory at "0x016ee5b8". The memory could not be written.

What can i do?.

The smallest file has 3855 elements (885 nodes) and biggest 121544 (62032 nodes). Both are tetrahedra mesh.

I'm using Win2K and XP with 1G in ram.
