help with permalinks redirect issue

I adjusted permalinks settings to use postname, and added in and adjusted platinum seo plugin to auto 301 new permlinks but…

Original link example here http://www.sunroomsuperstore.com/?p=40 still loads and stays at that url instead 301’ing to http://www.sunroomsuperstore.com/one which is the new url which also loads.

I don’t want this to become a nav/dup content issue but am unsure what I’m missing to fix this

Thanks
