WordPress MU

I'm getting this error when I create a new blog


WordPress database error: [Table 'myblog.wp_13_options' doesn't exist]
SELECT option_value FROM wp_13_options WHERE option_name = 'blogname' LIMIT 1

WordPress database error: [Table 'myblog.wp_13_options' doesn't exist]
SELECT option_value FROM wp_13_options WHERE option_name = 'post_count' LIMIT 1


What does this mean? And how do I fix it

Sorry I jumped the gun a little.
