This is the other thread about this bug.

I got one successful Poser run just now, and I loaded a character from the library, but Poser crashed on render. Next run, the library did not appear.

Perhaps something official or unofficial (spyware?) on the internet is messing about with or poking about in people's Poser runs' libraries.
