[kronolith] Calendar is not working

[amy at isot.com]

I get this error when try to use Calendar. Anybody know what I have to do to 
fix this. It was working before and one day this error came up. 

object(db_error)(7) { ["error_message_prefix"]=> string(0) "" ["mode"]=> int(1) 
["level"]=> int(1024) ["code"]=> int(-1) ["message"]=> string(23) "DB Error: 
unknown error" ["userinfo"]=> string(387) "SELECT DISTINCT e.event_id, 
e.event_recurtype FROM kronolith_events e WHERE e.calendar_id = 'amy' AND 
((e.event_start < '2003-12-01 00:00:00.000' AND e.event_end > '2003-11-01 
00:00:00.000') OR (e.event_recurenddate >= '2003-11-01 00:00:00.000' AND 
e.event_start <= '2003-12-01 00:00:00.000' AND e.event_recurtype != 0))
