Nathan has updated the memory problems in the windows version of 2.47, which were causing Blender to crash whenever memory requirements are high. The updated version is now available for download.
“The original release files were accidently built without LARGEADDRESSAWARE support. They have now been updated on September, 19th 2008. Click here for the checksums of the new binaries.”
You can find the download here on blender.org.
