pointing to wrong database after MT import

hi, I imported my MT blog to WP a few weeks ago. all went well. suddenly, my the home page of my blog is displaying my old blog instead of my new WP blog. All was well for about 3 weeks, and I went on vacation only to find that when I look at http://www.38harding.com/qblog, my lovely WP blog will not display, and my entries from the last 3 weeks are missing, and the ugly old MT template is controlling the display.

wp-admin still works when I log in, and I can even write posts, but somehow, the database from my old MT blog seems to have taken control over my site.

I just can’t figure out what went wrong, and I’ve reloaded my wp-config file again to make sure it’s pointing to the correct mysql db for wordpress. any suggestions?
