Setup Error

so i just loaded up the plugin, like i would any other plugin, it seemed to have worked, except when i click on the chat link, i get this message……

Query: SELECT userID, userName, userRole, channel, UNIX_TIMESTAMP(dateTime) AS timeStamp, ip FROM the1113211135414.ajax_chat_online ORDER BY userName; Error-Report: Table ‘the1113211135414.ajax_chat_online’ doesn’t exist Error-Code: 1146

what is it and how do i fix it? thanks in advance for the help!
