So, I Uninstall Poser, reinstall, add all the Service Releases, and it runs fine. 

Then I point it to the Runtime I have on another hard drive, and the message appears again?

I've been launching poser to that drive for months, without any major change in size, recently?  It's large, about 40GBs, but there's still about 40GBs left on the disk, and there are'nt a million things in any one folder?

I had'nt changed the the Edit > Preferences to Launch to Preferred State, so I expected it to run after it crashed after re-install, but it wo'nt.  This message comes up again!

This sytem has 750MBs RAM, 1GB Virtual Memory, and..well, 1 GB left on the C: Drive.  I'm going to try to increase the Virtual memory to 5.25GBs(750MBs + 2GBs for Windows, 2GBs for Poser, and then if I want to open Photoshop...)
