Removing Column In Fields

[[Stryder]]

]Ok, what i was installing told me to do this:

Run this SQL query on your database. Don't forget to add a prefix to table's name if you use one in your config.php:

ALTER TABLE `forum` ADD `hide_hack` INT(1) DEFAULT '0' NOT NULL;

I did that than began to recieve this message when going to edit forums.

Database error in vBulletin 3.0.7:
Invalid SQL: UPDATE jelsoft_forum SET
### UPDATE QUERY GENERATED BY fetch_query_sql() ###
