Quote - When you say "....delete the default character..", are you physically deleting the character from your runtime folder or deleting the character from the preview window in your application?  You need to be specific in order to help.

Generally, 3rd party content would be safe if you uninstall the application.  The Poser folder and the runtime Folder within will not disappear, only the application components.  Uninstallation will only target components originally installed with the program not anything else added afterwards unless they happen to be Service Release.

I don't even know what a runtime folder is so I'm guessing I just deleted him from the screen?

Thank you for letting me know everything will be safe!
