Did you uninstall Poser, then delete anything left in the Poser folder? You really should not just delete a program. If you didn't delete the folder after install, you really didn't change anything. Poser is weird that way. Once you've reinstalled, you want to right-click on the shortcut you use to run Poser, then choose Properties. change the "start in" section to reflect where the Poser program exists. Start Poser. Then set it up the way you want. Go to Edit Preferences, click the apporpiate choices. Then click a UI dot to make it final. Close Poser, then run it again. Bet it works right now.
