Before you re-installed Poser, you should make sure to get rid of any leftovers of the previous installation, by deleting the whole Poser 7 folder.

If you have content in there that you don't want to lose, by all means take a backup copy of the folder first... but that folder should be completely deleted before a fresh install.

Hope it helps...
