I followed the instuction from WordPress on moving your blog. When I click to gothe next page, I get a 404 message and the same happens when I click on on any posts. My Images also won't work, even though they are all there in the uploads folder.
Did you reset permalinks? Is your .htaccess writable?
If your host is yahoo.com, than you have more problems, because Yahoo hosting doesn't allow .htaccess files or permalinks.
