Incase you didn't get my e-mail, MatCreator...  It stops with a memory allocation error on my machine too. It was 42% done.   I had setup another try with some different render settings, but my husband wandered by, thought it didn't look like anything was going on, and shut down my computer.  Well, he tried to.  C5 asked him if he really wanted to cancel the render, and he said "Oh sh$t! My wife is going to kill me."  Since I run dual monitors, it seems to have removed my 2nd display window which is where the render que window sits.  Sheesh!  It didn't want to respond to anything, so I had to task kill it. :(  I'll try it again and my husband has been properly scolded to never touch my computers unless I tell him too. ;-)
