GeoffIX, I've finally used your suggestion of using the "archive and preserve users" reinstallation - it worked admirably well for Poser 5. Hooray! After so many months of frustration, I can use it again! (I don't have Poser 6 yet, so I don't know if it works as well for 6).

Poser 5 even "survived" all the updates I had to install afterwards, even using the traditional model.

I would definitely recommend that approach. I did not lose a single document, and although some of the network settings and Preferences disappeared (they were not so important for me), as well as all printers, the fundamental point is - it works.

Thanks a lot for that tip! It should be printed on bold, 80-pixel-font at e-Frontier's web site ;)
