Problems with Chatevents query for chat/buddychat module

Hi all

does anyone knows what does the following mean?

user warning: Table 'drupaltest.chatevents' doesn't exist query: SELECT * FROM chatevents WHERE 1171210544 - timestamp < 600 ORDER BY timestamp DESC LIMIT 10 in C:\p3t\public_php\Drupal\includes\database.mysql.inc on line 120.

I acknowledge there is no mysql or sql file comes with the chat / buddychat module.

How can i overcome this problem and get it working for my system and i have no idea why this error occured.

Thankyou for your time.
