bb, I already tried the LibraryPrefs.XML. renamed the paths as well as the main Poser directory name from Poser to Poser8. Unfortunately that doesn't seem to work as it no longer finds the main Poser directory libraries. I tried making the file read-only and that worked, but, since these files are continuously re-written by the application, Poser eventually crashed hehehe. I should've just deleted the preferences file altogether!! Instead i just went ahead and reinstalled into Poser8 directory and deleted all my preferences from previous installation.

That worked a treat! :D

Thank you for your invaluable help bagginsbill!
