Don't forget to backup your database before you do any changes. When I import FAQ sql, myadmin doesn't seem to add prefix 'zen_' automatically. So, I added this myself in the sql file (just use search and replace tool). I also deleted the previous imported FAQ tables before I imported them again so that duplicate error would not appear. You can paste the following sql to your myadmin once you are ready. (broken line is not included). Good luck!
