FROM prefix_datastore
WHERE title IN ('','options','bitfields','attachmentcache','forumcache','usergroupcache','stylecache','languagecache','products','pluginlist','cron','profilefield','userstats','birthdaycache','maxloggedin','iconcache','eventcache','mailqueue');

MySQL Error  : Table 'dbname_database.prefit_datastore' doesn't exist Error Number : 1146
Date         : Wednesday, June 20th 2007 @ 12:50:11 PM
Script       : http://www. my domain .com
Referrer     :

So far I can surf via admin area and members area with no problems... Is there anything I should be woried about?

You got the error before you installed the software. Likely someone browsing your site if not yourself.
