I did a simple install of One-Click Word Press. Is that why I apparently can't install plugins? Do I need to de-install that and reinstall custom? Will I lose my settings/data?
yes you will need a custom install.you could re-use the same database when you re-install. Since the old was a simple install there can't be any modified files, so re-using the database should bring all your settings and data with you.
Thanks so much, Lake. Really appreciate your help.
