Error at the line 25131: INSERT INTO `ubbt_FORUM_LAST_VISIT` (`FORUM_ID`, `USER_ID`, `LAST_VISIT_TIME`) VALUES(2, 2, 1291404700);

Query: INSERT INTO `ubbt_FORUM_LAST_VISIT` (`FORUM_ID`, `USER_ID`, `LAST_VISIT_TIME`) VALUES(2, 2, 1291404700);

MySQL: Duplicate entry '2-2' for key 1

Can anyone shed a little light on this please?
