I get that message sometimes too.  I haven't really figured out why, but I think it mostly happens when I've run really low on memory while using Poser and then had to reboot, or had to shut down suddenly when my PC froze up while using Poser. Sometimes after that when I start up Poser I then get the window message.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
