EUREKA...up above it ws stated that a complete install of Poser was to be done...but that really isn't necessary, is it ??? Can't you just dump the runtime...and any other files that were put in the Poser directory????? Then its all clean, and you can surely start over fresh.

Humankind has not woven the web of life. We are but one thread within it.
Whatever we do to the web, we do to ourselves. All things are bound together.
All things connect......Chief Seattle, 1854
