Permalink Problem after moving blog

Thanks to everyone here for getting me up and running, my blog is working across all browsers now. Here’s the new problem, and there have been several posts about it, but none explained what to do in this case:

I realized after doing the standard Yahoo install of WP that my blog was located at http://www.leftcoastlifestyle.com/blog and I wanted it at the root. I followed the instructions to move it to the root, and everything is there, but of course, when I click on a post permalink, I get a page not found. I can’t find the .htaccess file but I know I can modify it from the WP control panel, I have no idea what to do to get my permalinks rebuilt or whatever I need to do to get them to work.

Appreciate your help in advance…
