It dos sound like a bad character/morph file. When you load a figure such as Genesis DS reads al of the back-end assets (the stuff in /data/daz 3d/Genesis 8/Female/ in this case) so that it knows what properties to add to the Parameters pane, which UV sets to add to the Surfaces pane, how they all relate/trigger each other and so on. I would guess that something has a link to a file that isn't there, and so you get the warning. If you check the log file (Help>Troubleshooting>View Log File) and search for Bliss you should find a more complete error message that will tell you exactly which file is triggering the warning, you an then either uninstall it, ask the maker for a fix, or try editing it to fix it yourself.
