I have about 2600+ 404 Page not found errors and almost all of them are llokoing for things in my old 6.5 install directory.
Also, while I try to figure this out I am trying a program I happened to have (I forgot about it) called GSiteCrawl which is a free site map generator that will generate a site map for the entire site for both Goggle, Yahoo and others. This will be the first time I've tried it, so I'm hoping it will help.
