I've uninstalled Poser and discovered that the runtime folder was still around. Hopefully you have some extra room on your hard drive or you have a CD burner? I suggest you backup your runtime folder. You could use winzip or a similar archiving program. It might be best to go after some of the individual folders within runtime, such as geometries, libraries, etc. I did this one time, folder by folder.... zipping as I went along. I then copied the zip files to CD. I filled up one CD and started on another. And I've installed lots of stuff since then.
