All in One SEO plugin issue. Please Help

I don’t remember when exactly this happened..probably when I updated the plugin or the WP version. The problem is now All in one SEO plugin wants me to update few things in my database and reconfigure it. Does that mean I have lost all the meta descriptions I gave to my previous posts ? Because I don’t find them on the posts anymore when I do a Google sitesearch for my site. Will I get those descriptions back when I update the database ? Or did the plugin got screwed already ?
